Leviton LB250-S – Frequently Asked Questions

1) Will a Leviton LB215-S 2-pole breaker fit any load center, or only Leviton panels?
The LB215-S is a Leviton smart branch circuit breaker built for Leviton load centers and panelboards. It is a 2-pole device on a 120/240V system, which is the standard split-phase residential and light commercial service. If the panel on the job is a Square D or ABB load center, this is not the breaker for it; look at the Square D PowerPacT B thermal magnetic breaker or the Square D Multi9 C60 line for those panels instead.
2) Is a 10kA interrupt rating enough for my service?
10kA is the short circuit current rating on the Leviton smart 2-pole breaker, and it covers typical residential and light commercial panelboards where available fault current at the panel stays under that. On a large commercial service with high available fault current, you need a higher AIC device, a molded case breaker such as the ABB A2N Series or the Square D PowerPacT Q I-Line. Get the available fault current at the panel from the utility or the coordination study before you decide.
3) I need a DIN rail mounted breaker for a control panel. Does the Leviton LB2-S work?
No. The Leviton LB215-S is a plug-in branch breaker for a load center, not a DIN rail device. For a DIN rail control panel, the Square D C60 UL489 miniature circuit breaker is DIN rail mount, and the ABB ST200M is a UL1077 supplementary protector on DIN rail. Note the difference between those two: UL489 is a branch circuit breaker, UL1077 is supplementary protection and cannot serve as branch circuit overcurrent protection.
4) I have a 3-phase panel. Will a 2-pole Leviton smart breaker work?
Not for a 3-phase load. The Leviton smart breaker is 2-pole on 120/240V, which is single-phase split service. Three-phase feeders and motor loads need a 3-pole device, for example the ABB A2N Series 3-pole molded case breaker, the ABB E150 Series 3-pole thermal magnetic breaker, or the ABB XT4 Series 3-pole kit.
5) What 2-pole 15A breaker should I use if the circuit is a single hot leg at 120V instead of a double-pole load?
A 2-pole device is the wrong shape for a single hot leg. The Leviton LB215-S is a 2-pole configuration intended for double-pole circuits at 120/240V. For a single 120V AC branch, the Square D Multi9 C60 1-pole C-curve miniature circuit breaker is a 1-pole device rated 120V AC, with a C trip curve suited to moderate inrush loads. Match the pole count to the number of ungrounded conductors the circuit actually carries.
6) What amperages does the Leviton LB2-S smart 2-pole breaker come in?
Four: 15A (LB215-S), 20A (LB220-S), 50A (LB250-S) and 60A (LB260-S). All four are 2-pole. That spread covers the usual double-pole loads, 15A and 20A for 240V baseboard heat or a small compressor, 50A for a range or an EV circuit, 60A for a subfeed or larger appliance.
7) Can a Leviton smart 2-pole breaker go in an unheated garage or an outdoor panel?
Operating temperature runs down to -40 degrees Celsius, so cold is not the limiting factor in an unheated garage, an attic, or a detached outbuilding. What governs an outdoor installation is the enclosure rating of the load center itself, not the breaker.
8) What makes this a smart breaker, and do I still get protection if the network drops?
The Leviton LB215-S is a smart branch circuit breaker, meaning it carries circuit monitoring on top of overcurrent protection in a Leviton panelboard. The overcurrent and short circuit protection is the breaker's own mechanism, rated 15A with a 10kA interrupt, and it works whether or not the monitoring side is talking to anything. Losing connectivity costs you the monitoring data, not the trip.
9) For a 240V baseboard heater circuit, do I order the 15A or the 20A Leviton smart breaker?
That follows the conductor and the heater load, not the breaker. The 15A LB215-S protects a 14 AWG copper branch circuit, the 20A LB220-S protects 12 AWG. Both are 2-pole 120/240V devices with the same 10kA interrupt rating, so the only difference across that pair is the trip rating.
10) When do I need a molded case breaker instead of a 2-pole branch breaker like the Leviton LB215-S?
Branch circuit protection and feeder or service protection are different jobs. The Leviton LB215-S covers branch circuits at 15A, 120/240V, 2 poles, with a 10 kiloamp interrupt rating. For three-phase feeders and higher-capacity distribution, the ABB A2N Series 3-pole molded case circuit breaker is UL listed and carries three poles, and the Square D PowerPacT B is a thermal magnetic molded case breaker. Molded case devices bolt or plug into distribution gear rather than a residential load center, so the enclosure and bus arrangement decide as much as the rating does.
11) I need a 3-pole thermal magnetic breaker for a three-phase panel, not the Leviton 2-pole. What are the options?
The Leviton LB215-S line is 2-pole only, across its 15A, 20A, 50A and 60A amperage options. For three-phase work, the ABB E150 Series is a 3-pole thermal magnetic circuit breaker, the ABB XT4 Series is a 3-pole molded case breaker kit, and the ABB A2N Series is a UL listed 3-pole molded case breaker. Pick by the gear the breaker has to land in, since molded case frames and panelboard-mount breakers are not interchangeable.
12) Does a Square D PowerPacT Q I-Line breaker fit the same panel as a Leviton LB215-S?
No. The Square D PowerPacT Q is an I-Line circuit breaker, which mounts to the I-Line bus arrangement used in Square D distribution panelboards. The Leviton LB215-S is a 2-pole branch circuit breaker for residential and light commercial panelboards and load centers. Confirm the bus and mounting style of the panel on site before ordering either one, because the amperage matching on its own will not tell you whether the breaker seats.
13) Are Leviton LB2-S smart breakers made in the USA?
Country of origin on the Leviton smart 2-pole breaker is China. That matters on public work with domestic sourcing requirements, so check it against the spec before you submit.
14) How much does a Leviton 2-pole smart breaker weigh for shipping a panel build?
0.85 pounds each. On a panel build with a dozen 2-pole breakers, that is roughly 10 pounds of breakers before the load center itself.
