Choosing a circuit breaker smart panel starts with a basic distinction: some picks are smart breakers for a compatible home load center, while others are DIN-rail devices intended for a different electrical setup. My leading choices reflect those different needs. The Leviton LB120-DST adds AFCI/GFCI protection and app control in a compatible Leviton panel; the Aeliussine 1–63A adjustable Wi-Fi breaker offers threshold-based monitoring and automation; and the Leviton LB120-ST suits buyers who want simpler remote circuit control within Leviton’s ecosystem.

The main tradeoff is panel compatibility versus feature flexibility. Leviton breakers are built for compatible Leviton Load Centers and require a Whole Home Energy Monitor, while the Aeliussine models use DIN-rail mounting and Smart Life/Tuya. The Aeliussine options offer adjustable electrical thresholds and broader scheduling, but their listed details leave installation and connectivity requirements less clear. I rank these products by how clearly their stated features serve a defined smart-panel use, while treating electrical compatibility and safety as prerequisites rather than afterthoughts.

Key Takeaways
- The Leviton LB120-DST is the only listed pick combining smart controls with both AFCI and GFCI protection, but it needs a compatible Leviton Load Center and Whole Home Energy Monitor.
- The Leviton LB120-ST provides app control and scheduling without the listed dual-function AFCI/GFCI feature; its Leviton ecosystem requirements remain the same.
- Aeliussine’s DIN-rail breakers add adjustable over-current, over-voltage, and over-power thresholds, unlike the Leviton breakers described here.
- The Aeliussine 4-pack is the bulk option for buyers planning several compatible DIN-rail circuits, while the 2-pack is a smaller commitment.
- None of these products should be treated as a universal replacement for a panel breaker; verify panel or DIN-rail compatibility and consult a qualified electrician.

More Details on Our Top Picks
Leviton LB120-DST 2nd Gen Smart Dual-Function AFCI/GFCI Circuit Breaker, 20 A, 120 V
I rank the Leviton LB120-DST first because it pairs app-based circuit control with a protection feature set the other options do not list: dual-function AFCI/GFCI protection. That makes it the strongest fit for a buyer upgrading a compatible Leviton Load Center who wants smart scheduling and remote on/off control without giving up those two types of circuit protection. It also provides home energy consumption insights through the My Leviton system.
Its advantage is specific, not universal. Compared with the Aeliussine DIN-rail models, the LB120-DST is tied to a named load-center ecosystem and does not list adjustable over-current, over-voltage, or over-power thresholds. Compared with the simpler LB120-ST, it adds AFCI/GFCI protection, making it the more feature-rich Leviton pick when that protection is appropriate for the circuit. The major constraint is the required Whole Home Energy Monitor, alongside panel compatibility. Buyers should confirm both the exact load-center fit and installation requirements before choosing it.
This is my top recommendation only for the right Leviton installation. If your panel is not compatible, its smart functions do not make it a practical substitute for a DIN-rail breaker. And if the goal is adjustable threshold monitoring across a DIN-rail setup, Aeliussine’s product descriptions align more closely with that use.
Pros:- Combines AFCI and GFCI protection with smart controls
- Offers remote on/off control and scheduling through My Leviton
- Provides home energy consumption insights
- Has a clearly stated 20 A, 120 V, single-pole format
Cons:- Requires a compatible Leviton Load Center
- Requires the Whole Home Energy Monitor to operate
- Does not list adjustable over-voltage or over-power thresholds
Best for: Owners of a compatible Leviton Load Center seeking app control, scheduling, energy insights, and dual AFCI/GFCI protection in a 20 A, 120 V breaker.
Not ideal for: Buyers with another panel brand, a DIN-rail installation, or no plan to use the required Whole Home Energy Monitor.
- Model:LB120-DST, 2nd Gen
- Breaker type:Dual-function AFCI/GFCI
- Amperage:20 A
- Voltage:120 V
- Poles:1
- Mounting:Snap-in
- Panel compatibility:Compatible Leviton Load Center
- Required accessory:Whole Home Energy Monitor (LWHEM)
- App control:My Leviton remote on/off and scheduling
Our verdict“For a compatible Leviton panel, this is the most protection-focused smart pick in the group, provided you accept its required monitor and ecosystem limits.”
WiFi Smart Circuit Breaker, 1–63 A, DIN Rail Mount
This single Aeliussine DIN-rail smart breaker is my pick for buyers who want the listed threshold and monitoring features without choosing a multi-unit pack. It supports adjustable current protection from 1–63 A, with configurable over-current, over-voltage, and over-power thresholds. The Smart Life/Tuya app adds alerts, electrical monitoring, usage reports, remote control, and timer-based automation. Alexa and Google Home support gives it more control routes than the Leviton options in this lineup, which are described through My Leviton.
Compared with the Aeliussine 2-pack, this listing is a more straightforward choice when a buyer needs one DIN-rail device rather than two. Its stated feature set is close to the other Aeliussine entries, so the main distinction is quantity rather than a different protection or app platform. Compared with the Leviton LB120-DST, it offers adjustable thresholds but does not list AFCI/GFCI protection or a snap-in fit for a household Leviton panel. That makes electrical-format verification essential: DIN rail is not a general promise of compatibility with a residential load center.
The product’s smart functions depend on a compatible Wi-Fi connection and app setup. The available description does not spell out network details, installation requirements, or which electrical systems are suitable. I would choose it only after confirming the device’s ratings and installation fit with a qualified electrician, rather than relying on the broad 1–63 A range alone.
Pros:- Adjustable 1–63 A current protection range
- Configurable over-current, over-voltage, and over-power thresholds
- App alerts, electrical monitoring, usage reports, and remote control
- Lists Alexa and Google Home compatibility
Cons:- Requires compatible Wi-Fi and app setup for smart functions
- DIN-rail format may not fit a standard residential load center
- Installation and connectivity details are not fully specified
Best for: Buyers needing one DIN-rail device with adjustable protection thresholds, app monitoring, and remote automation for a verified compatible installation.
Not ideal for: Anyone seeking a direct-fit breaker for a conventional panel without confirming DIN-rail compatibility, or buyers who prioritize listed AFCI/GFCI protection.
- Model:DLQ-Wifi
- Voltage:AC 90–300 V
- Adjustable current range:1–63 A
- Breaker type:Standard
- Poles:2
- Mounting:DIN rail
- App:Smart Life/Tuya
- Voice assistants:Alexa, Google Home
Our verdict“Choose this single-unit Aeliussine when adjustable monitoring matters and your electrician confirms the DIN-rail device suits the installation.”
Leviton LB120-ST 2nd Gen Smart Circuit Breaker, 1-Pole, 20 Amp, 120 Volt
The Leviton LB120-ST is the simpler Leviton choice: it brings remote on/off control, scheduling by time and day, and energy-use insights to a compatible 20 A, 120 V circuit. That feature mix makes sense when the buyer’s priority is managing a circuit through the My Leviton app, rather than adjusting electrical protection thresholds. Its snap-in format also gives it a clearer intended home than the Aeliussine DIN-rail breakers, but only inside a compatible Leviton Load Center.
Compared with the LB120-DST, the LB120-ST does not list dual-function AFCI/GFCI protection. Buyers choosing between the two should not treat that as a minor feature difference: confirm which protection type is called for on the circuit and select the correct breaker for the application. The DST is the stronger choice when its additional protection is needed; the ST is the more focused option when app control and scheduling are the stated goal.
Like the other Leviton model here, the LB120-ST requires a Whole Home Energy Monitor to operate, so it is not a standalone smart-breaker purchase. It also will not answer the needs of someone looking for adjustable over-voltage or over-power thresholds, which are listed on the Aeliussine devices. I would place it below the DST because its protection description is narrower, while still recommending it to buyers who have the right Leviton panel and want a more basic app-controlled circuit.
Pros:- Provides remote on/off control through My Leviton
- Supports schedules by time and day
- Offers home energy-use insights
- Uses a stated single-pole, 20 A, 120 V format
Cons:- Requires a compatible Leviton Load Center
- Requires the Whole Home Energy Monitor to operate
- Does not list dual-function AFCI/GFCI protection
Best for: Leviton Load Center owners who want remote circuit switching, weekly scheduling, and energy insights on a 20 A, 120 V circuit.
Not ideal for: Buyers seeking listed AFCI/GFCI protection, adjustable protection thresholds, or a smart breaker for a non-Leviton panel.
- Model:LB120-ST, 2nd Gen
- Poles:1
- Amperage:20 A
- Voltage:120 V
- Mounting:Snap-in
- Panel compatibility:Compatible Leviton Load Center
- Required accessory:Whole Home Energy Monitor (LWHEM)
- App:My Leviton
Our verdict“This is the Leviton pick for app-based control and scheduling when dual-function protection is not the feature driving the choice.”
Aeliussine WiFi Smart Switch and Circuit Breaker, 90–300V, 1–63A, 2-Pack
The Aeliussine 2-pack suits a project that calls for two smart switching points in a compatible DIN-rail setup. Each device is described with a 90–300 V range and 1–63 A capacity, plus real-time current, voltage, and active-power monitoring. Adjustable thresholds can trigger app alerts and automatic shutoff, while Smart Life/Tuya adds remote control, energy reports, and scheduling. Alexa and Google Home support round out its automation options.
The feature set closely tracks the single Aeliussine breaker in this roundup. The meaningful distinction is the two-device quantity, which may be useful when planning a paired installation rather than buying one unit at a time. Compared with the 4-pack, it asks for a smaller commitment and may better match a limited project. Compared with Leviton’s snap-in products, it offers broader adjustable threshold features but lacks their clearly named Leviton load-center fit and the LB120-DST’s listed AFCI/GFCI protection.
I would not read “2-pack” or the wide voltage range as evidence that the devices suit any two circuits. The product description does not specify detailed installation requirements or app connectivity particulars, and the DIN-rail format must match the enclosure and system. This is a sensible role-based pick for a verified DIN-rail project, but not a shortcut around panel compatibility checks.
Pros:- Two devices for projects needing more than one smart switching point
- Monitors current, voltage, and active power in real time
- Supports adjustable thresholds, alerts, and automatic shutoff
- Includes remote control, scheduling, energy reports, and voice-assistant support
Cons:- Requires a compatible electrical setup and DIN-rail mounting
- Installation requirements and app connectivity details are not specified
- Does not list AFCI/GFCI protection
Best for: Buyers planning a two-device DIN-rail installation who want app monitoring, adjustable electrical thresholds, and voice-assistant support.
Not ideal for: Those needing a single replacement breaker for a standard load center, or buyers who need clearly specified installation instructions before purchase.
- Brand:Aeliussine
- Model:DLQ-Wifi
- Voltage:90–300 V
- Current range:1–63 A
- Breaker type:Standard
- Poles:2
- Mounting:DIN rail
- Pack quantity:2
- App and voice control:Smart Life/Tuya; Alexa and Google Home
Our verdict“Pick the 2-pack over the single unit when a verified DIN-rail project calls for two devices and its threshold features fit your needs.”
Aeliussine 1–63A Adjustable Wi-Fi Smart Circuit Breaker, 4-Pack
This Aeliussine 4-pack is the broadest quantity option in the roundup. It is aimed at buyers planning several compatible DIN-rail circuits and wanting a consistent Smart Life/Tuya setup across them. The listed functions include adjustable over-current, over-voltage, and over-power thresholds, app alerts and automatic shutoff, remote control, energy reports, and several scheduling modes: timer, countdown, cycle, and sunrise/sunset. Alexa and Google Home support is also listed.
Against the 2-pack, the practical difference is project scale, not a distinct breaker feature set. If the installation needs only one or two devices, the 4-pack adds units the buyer may not use; if several circuits are planned, it may simplify sourcing matching models. The single Aeliussine listing is the more restrained route for one device. Leviton remains the alternative for a compatible residential load center and, in the DST’s case, listed AFCI/GFCI protection. Aeliussine’s DIN-rail mounting and adjustable threshold approach serve a different installation and should not be treated as an interchangeable Leviton replacement.
The description does not supply detailed installation requirements, and it does not establish compatibility with a specific panel or enclosure. App-based features also require Wi-Fi and setup. I would only select the bulk pack after an electrician confirms the device ratings, mounting arrangement, and intended circuit use. Its extra scheduling modes help automation planning, but they do not resolve the central question of whether this breaker belongs in your electrical system.
Pros:- Four matching devices for a multi-circuit project
- Adjustable over-current, over-voltage, and over-power thresholds
- Provides app alerts, remote control, and energy reports
- Lists timer, countdown, cycle, sunrise/sunset, and voice-assistant automation
Cons:- Requires Wi-Fi and app setup for smart features
- DIN-rail compatibility must be confirmed for the installation
- Bulk quantity may exceed the needs of a small project
Best for: Buyers with a verified DIN-rail installation who plan to add smart monitoring and automation to several circuits using matching devices.
Not ideal for: People replacing one breaker, those with a conventional panel that does not accept DIN-rail devices, or buyers requiring listed AFCI/GFCI protection.
- Brand:Aeliussine
- Model:DLQ-Wifi
- Current range:1–63 A
- Breaker type:Standard
- Poles:2
- Mounting:DIN rail
- Pack quantity:4
- App:Smart Life/Tuya
- Voice assistants:Alexa, Google Home
Our verdict“The 4-pack is the project-scale choice for several confirmed DIN-rail circuits, not a better substitute for a breaker matched to another panel format.”
How We Picked
I ranked these five products for the specific job implied by circuit breaker smart panel: bringing circuit-level control, monitoring, or protection features into an electrical installation. I compared the stated protection functions, monitoring and app controls, installation format, ecosystem dependencies, and practical scope of each option. I gave extra weight to whether a product’s stated role is clear enough for a buyer to match it to an existing panel or electrical enclosure.
The lineup splits into two distinct groups. The Leviton breakers are snap-in products for compatible Leviton Load Centers, and both require the Whole Home Energy Monitor. The Aeliussine breakers mount on DIN rail, use Smart Life/Tuya, and list adjustable electrical thresholds. Those are not interchangeable formats. I did not treat voice-assistant support, pack quantity, or a long feature list as proof of broad panel compatibility. The ranking reflects suitability for a defined buyer, not a claim that any breaker fits every home. Product details supplied for this roundup do not establish certifications, exact installation rules, Wi-Fi band requirements, or compatibility with a specific panel model, so buyers should verify those points before purchase.

Factors to Consider When Choosing Circuit Breaker Smart Panel
I would make the panel fit the first decision, then compare smart features. These products divide into snap-in Leviton breakers for compatible Leviton Load Centers and DIN-rail Aeliussine devices. A feature comparison matters only after the proposed breaker is confirmed for the circuit and enclosure.Start with the panel or enclosure
Read the panel label and identify its manufacturer and model before selecting a breaker. The two Leviton LB120 models are specified for compatible Leviton Load Centers; the Aeliussine options list DIN-rail mounting. Those formats are not automatically interchangeable. Ask a qualified electrician to verify the exact breaker fit, circuit rating, and installation requirements rather than relying on appearance or a broad voltage range.
Choose protection before app features
The LB120-DST is the only product here described with dual AFCI/GFCI protection. The LB120-ST is described as a smart circuit breaker without that dual-function label, while Aeliussine lists adjustable over-current, over-voltage, and over-power thresholds. These functions are not equivalent. Match protection to the circuit and applicable electrical requirements; do not select a device based on smart controls alone or assume adjustable thresholds replace a particular protection type.
Compare monitoring and control needs
Aeliussine’s descriptions emphasize live electrical values, app reports, configurable thresholds, and automation through Smart Life/Tuya. Leviton emphasizes remote switching, schedules, and home energy insights in My Leviton. If you want to monitor electrical readings and set thresholds, the Aeliussine feature descriptions are more aligned. If your installation is already in the Leviton ecosystem and you want scheduled circuit control, the Leviton options may fit better. Voice-assistant support is listed for Aeliussine, not for the Leviton models in the supplied details.
Account for required accessories and network setup
Both Leviton breakers require the Whole Home Energy Monitor to operate, so include that system in your planning and verify how it works with your load center. Aeliussine smart functions rely on an app and Wi-Fi, but the descriptions do not specify all connectivity details. Before committing, confirm the network requirements, supported app setup, and what happens to basic breaker functions if the network or cloud connection is unavailable.
Match pack size to the project
The single Aeliussine listing makes the most sense for one planned device, the 2-pack is aimed at two compatible DIN-rail positions, and the 4-pack serves larger multi-circuit projects. Pack size does not change the stated mounting format or make a model more compatible with a residential panel. I would count the circuits and confirm the device is suitable for each one before selecting a quantity.
Treat installation as electrical work
A circuit breaker is a protective device, not a general-purpose smart switch. Correct selection and installation depend on system voltage, circuit requirements, panel compatibility, and local rules. Product descriptions in this roundup do not establish suitability for every jurisdiction or installation. Have a qualified electrician verify ratings and fit, and do not work inside an energized panel. Smart monitoring should supplement, not replace, proper protection and safe installation.
Frequently Asked Questions
Will these smart breakers fit any electrical panel?
No. The Leviton models are specified for compatible Leviton Load Centers, while the Aeliussine devices are DIN-rail mounted. A breaker must match the panel or enclosure and the circuit’s electrical requirements. Check the panel documentation and ask a qualified electrician to verify compatibility before buying or installing any of these products.
Which product offers AFCI and GFCI protection?
The Leviton LB120-DST is the only listed product described as a dual-function AFCI/GFCI breaker. The LB120-ST and Aeliussine models have different stated functions and should not be assumed to provide the same protection. Confirm which breaker type is required for the specific circuit and installation.
Do the Leviton smart breakers work without another device?
The product details state that both the LB120-DST and LB120-ST require a Leviton Whole Home Energy Monitor to operate. They also require a compatible Leviton Load Center. Check accessory and system compatibility before choosing either model, since the breaker alone does not supply the complete smart-control setup described.
What is the main difference between the Aeliussine options?
The main difference in the supplied descriptions is quantity: one device, a 2-pack, or a 4-pack. Their shared feature emphasis includes DIN-rail mounting, Smart Life/Tuya control, and adjustable protection thresholds; the 4-pack description also lists several scheduling modes. Select a quantity that matches a confirmed project, but verify ratings and installation suitability for every intended circuit.
Can app control replace a conventional breaker’s protective role?
No. Remote control, scheduling, alerts, and energy reports are smart features, not a reason to disregard proper breaker selection or required circuit protection. Choose a breaker that matches the panel, circuit, and applicable requirements, and use a qualified electrician for installation. App access should be treated as an added control layer rather than a substitute for safe electrical design.
Conclusion
My recommendations depend on the installation. For a compatible Leviton Load Center where dual-function protection and app control are both priorities, I would start with the LB120-DST, while planning for its required Whole Home Energy Monitor. Choose the LB120-ST if your goal is simpler remote switching and scheduling in that same Leviton ecosystem and its stated protection features match the circuit. For a confirmed DIN-rail project needing adjustable thresholds and app monitoring, the single Aeliussine model suits one device, the 2-pack suits a small multi-device job, and the 4-pack fits a larger planned installation. In every case, I would verify panel fit, circuit ratings, and installation requirements with a qualified electrician before buying; smart controls cannot make an incompatible breaker suitable.
