Leviton LWHEM-2 Smart Circuit Breaker Hub
The Leviton LWHEM-2 Smart Circuit Breaker Hub is built to connect and coordinate Leviton smart circuit breakers within a single electrical panel, giving installers and homeowners a centralized point for monitoring and control. As a hub device, the LWHEM-2 links compatible smart breakers together so panel-level activity can be tracked and managed from one connected system. Leviton designs this hub to support smarter, more connected residential and light commercial electrical distribution, bringing modern monitoring capability to standard breaker panels. Because it is purpose-built for the Leviton smart breaker lineup, the LWHEM-2 is intended to be installed and configured as part of a broader Leviton smart electrical setup rather than as a standalone accessory.
Key Features
- Smart Hub Functionality: Serves as the central communication point for Leviton smart circuit breakers installed in the same panel.

Why Leviton?
Leviton is a long-established manufacturer of electrical wiring devices, breakers, and connected home solutions used by electrical professionals and homeowners alike. The LWHEM-2 Smart Circuit Breaker Hub extends that expertise into panel-level connectivity, helping tie individual smart breakers into one coordinated system rather than leaving each breaker to operate in isolation. Choosing Leviton for this hub means pairing it with a brand built around dependable, code-compliant electrical products, and it gives installers a single, familiar source for both the breakers and the hub that ties them together. For electricians and property owners already standardized on Leviton smart electrical equipment, the LWHEM-2 is a natural addition that keeps panel management within one connected, manufacturer-supported system.

Leviton LWHEM-2 – Frequently Asked Questions
1) What does the Leviton LWHEM-2 actually do in a panel?
The LWHEM-2 is a hub, not a breaker that protects a circuit. It acts as the central communication point for Leviton smart circuit breakers installed in the same panel, pulling breaker-level data together so circuit activity across the panel can be viewed and managed from one connected system. It does not add overcurrent protection of its own.
2) Will the Leviton smart breaker hub work with Square D or ABB breakers in my panel?
No. The hub communicates with Leviton smart breakers only, and it is built to interoperate with other Leviton smart electrical products. Conventional breakers from other makers, such as the Square D PowerPacT B thermal magnetic breaker or the ABB E150 Series 3-pole thermal magnetic breaker, are not connected devices and cannot report to it. If your panel is Square D or ABB, you are replacing breakers with standard protective devices, not adding monitoring.
3) I want per-circuit energy monitoring in an existing panel. Does this hub do that by itself?
The hub supplies the panel-level visibility and home energy monitoring function, but the per-circuit data comes from the Leviton smart breakers it is paired with. Budget the job as hub plus one smart breaker for each circuit you want to see, and plan on the panel being a Leviton load center setup so the smart breakers fit.
4) We are standardized on Square D panels. Does the LWHEM-2 still make sense for us?
The LWHEM-2 is purpose-built for the Leviton smart breaker lineup and is meant to be installed and configured as part of a broader Leviton smart electrical setup, so it pairs with Leviton smart breakers in a Leviton load center. A facility standardized on Square D would be filling breaker positions with devices from that line - the PowerPacT B thermal magnetic breaker, the PowerPacT Q I-Line breaker, or the Multi9 C60 miniature breaker - and would not add the Leviton hub to those panels.
5) Is the Leviton LWHEM-2 a circuit breaker that protects a circuit, or something else?
The LWHEM-2 is a Smart Circuit Breaker Hub. It is the communication device that links Leviton smart breakers in a panel so breaker-level data can be monitored and managed from one connected system - it is not the overcurrent protective device for a branch circuit. If what you need is an actual breaker to carry and protect a load, that is a different part: a molded case breaker such as the Square D PowerPacT B thermal magnetic circuit breaker, or a miniature breaker such as the Square D Multi9 C60 1-pole C-curve unit. The hub and the breakers are complementary, not alternatives.
6) I need a 3-pole breaker for a smart panel job - can the LWHEM-2 be used for that?
No. The LWHEM-2 has no pole rating because it is a hub for Leviton smart breaker communication rather than a switching and protective device. For 3-pole duty, look at the ABB A2A150TT in the A2 Series molded case line, the ABB E150 Series 3-pole thermal magnetic breaker, or the Square D PowerPacT Q I-Line breaker. The LWHEM-2 would be ordered alongside Leviton smart breakers in the same panel, not in place of a 3-pole device.
7) Is the LWHEM-2 suitable for a commercial building panel or just houses?
Leviton positions the hub for residential smart panels and load centers as well as light commercial electrical distribution, including connected panel upgrades and retrofits. For heavier commercial distribution gear, molded case and I-Line devices are the usual territory, such as the ABB A2N Series 3-pole molded case breaker or the Square D PowerPacT Q I-Line breaker, and neither of those is a monitored smart breaker the hub can talk to.
8) What part number do I order for the Leviton smart breaker hub?
Order it as Leviton LWHEM-2. It is a single-model item with no finish, pole, or amperage options to specify, so the breakers themselves are where your circuit selections get made.
9) What is the difference between ordering the LWHEM-2 and ordering a breaker kit like the ABB MBB33?
They solve different problems. The ABB MBB33 is an XT4 Series 3-pole molded case circuit breaker kit, meaning hardware supporting a breaker installation in an ABB panel. The Leviton LWHEM-2 is a monitoring and control hub that aggregates breaker-level data from compatible Leviton smart breakers so circuit activity across the panel can be viewed from one connected device. Ordering the LWHEM-2 gets you panel visibility; ordering the MBB33 gets you breaker hardware.
