Leviton LDATA Smart Breaker Data Hub

The LDATA is the data hub that makes a Leviton Load Center smart. It installs into the load center and gives the breakers a connection back to the My Leviton app, so you can monitor circuits and trip breakers remotely and push firmware updates to the panel. It is not a breaker itself and it does not protect a circuit, so it never replaces a branch breaker position's protective function. Connection is by Wi-Fi or hardwired Ethernet, so a panel in a basement or a metal enclosure can be wired rather than relying on signal.

No. The LDATA hub is built to install into a Leviton Load Center and communicates with Leviton smart breakers, so it has no function in a Square D QO/PowerPacT or ABB panel. If you are working in one of those panels you are buying standard protective breakers instead, such as the Square D Multi9 C60 1-pole or the ABB E150 Series 3-pole thermal magnetic breaker, and panel monitoring would have to come from that manufacturer's own system.

The LDATA hub works with 120 VAC, 1-pole branch breakers at 15 A and 20 A. That covers the standard lighting and receptacle circuits in a residential or light commercial panel. Multi-pole 240 V loads (dryer, range, HVAC) are outside that range, so plan the smart-monitored circuits around single-pole 15 A and 20 A positions.

No, they do different jobs. The Square D Multi9 C60 is a 1-pole C-curve miniature circuit breaker rated 120V AC, so it provides overcurrent protection for a branch circuit. The Leviton LDATA is a smart breaker data hub that installs into a Leviton Load Center to make it smart, adding Wi-Fi or Ethernet connection for remote monitoring and tripping and single-app control through My Leviton. If the goal is protecting a circuit, the C60 is the breaker; if the goal is adding monitoring to a Leviton panel, the LDATA is the part, and a panel still needs its own branch breakers either way.

The LDATA is a 1-pole, 120 VAC device and is a data hub rather than a feeder protective device, so it does not serve a three-phase feeder. For a 3-pole molded case breaker, the ABB A2N Series 3-pole molded case circuit breaker is UL listed and comes from the A2 Series, and the Square D PowerPacT B thermal magnetic breaker is another molded case option. The ABB E150 Series is a 3-pole thermal magnetic breaker as well. Any of those is selected on frame, trip rating and interrupting capacity for the feeder, and none of them provides the app monitoring the LDATA adds to a Leviton Load Center.

The Leviton LDATA is built to install into a Leviton Load Center, so it is tied to that enclosure. For a DIN rail assembly, the Square D C60 UL489 miniature circuit breaker is a DIN rail mount device, and the ABB ST200M miniature circuit breaker is built to UL1077. The distinction between those two matters on a job: UL489 covers branch circuit protection, while UL1077 covers supplementary protection, so the ST200M is used downstream of a branch breaker rather than as one.

Operating temperature is -40 C to 85 C, so cold garages, attics, and unconditioned mechanical rooms are within range. That span covers essentially any climate in North America. The enclosure it sits in still governs moisture and dust exposure, so the load center itself has to be rated for the location.

Not necessarily. The LDATA hub takes either a Wi-Fi or an Ethernet connection, so if the panel sits in a basement or garage where the wireless signal drops out, you can run a cable to it instead. For property managers standardizing across a building, the Ethernet option is usually the one that survives tenant router changes.

Yes, My Leviton handles both. The same app that controls the Leviton Smart Load Center through the LDATA hub also controls the Decora Smart Wi-Fi device lines, so lighting controls and panel monitoring live in one place rather than two apps. That matters on multi-family and hospitality jobs where maintenance staff will only realistically learn one interface.

No. The ABB MBB33 is an XT4 Series 3-pole molded case circuit breaker kit, so it is breaker hardware for an XT4 frame. The Leviton LDATA is a data hub that goes into a Leviton Load Center to give the panel Wi-Fi or Ethernet connectivity and single-app control alongside the Decora Smart Wi-Fi product lines. They are not interchangeable in either direction, and the LDATA is specific to Leviton panels rather than a universal add-on for another manufacturer's breaker.

One part number, LDATA. There are no finish, amperage, or connection variants to specify, so the ordering decision is just quantity, one per load center. The Wi-Fi versus Ethernet choice is made at install, not at order time.

The Leviton LDATA carries an operating temperature range of -40 C to 85 C, which covers unheated and outdoor-rated enclosures on the electronics side. For the protective devices in the same enclosure, the ABB A2N Series molded case breaker is UL listed and the Square D PowerPacT Q is an I-Line breaker for panelboard applications, and the correct choice among those is driven by the enclosure and bus arrangement rather than by the hub. Confirm the enclosure rating for the location, since the temperature range of a device inside it does not by itself make the enclosure suitable.
