Leviton LB290 – Frequently Asked Questions

1) Is the Leviton LB290 a plug-in breaker or does it need a bolt-on kit?
Plug-on mount. The LB290 snaps straight onto the bus bars in a compatible Leviton load center, so there's no mounting hardware to order separately and no bolting to the bus. That's what makes it quick on a service call: kill the main, pull the old breaker, push the new one on. It's a standard branch breaker, not a main or a feeder device.
2) What amperages does the Leviton LB2 series 2-pole breaker come in?
Two ratings: 90A as the LB290 and 125A as the LB212. Both are 2-pole plug-on devices. If you're feeding a sub-panel or a large piece of equipment and the calculated load lands above 90 amps, take the LB212 rather than the LB290.
3) Will a Leviton LB290 fit in a Square D or ABB panel?
No. Plug-on breakers are only listed for the panelboard family they were designed for, and the LB290 is a Leviton plug-on device for Leviton load centers. Dropping it into another manufacturer's panel is not a listed combination even if the bus stab looks similar. If you're working in a Square D panel, stay in the Square D line, and for ABB gear stay with ABB. Check the label inside your panel door for the breaker types it accepts before you order.
4) Is the Leviton LB290 a standard thermal-magnetic breaker or does it have GFCI or AFCI protection?
Standard branch breaker, overcurrent protection only. It trips on overload and short circuit and has no ground fault or arc fault sensing. If the circuit you're protecting needs GFCI or AFCI per code for the room or the equipment, you need a dedicated GFCI or AFCI breaker in the Leviton line instead, or device-level protection downstream.
5) Is the ABB ST200M miniature circuit breaker an equivalent to the Leviton LB290?
They are not interchangeable. The ABB ST200M is a miniature circuit breaker built to UL1077, which is the supplementary protector standard rather than the branch circuit standard. The Leviton LB290 is a standard branch circuit breaker providing overcurrent protection for branch circuit wiring in a panelboard. Where the job calls for branch circuit protection in a load center, the ST200M is not a substitute for it. The Square D C60 in the comparable set is the UL489 miniature breaker, which is the branch-rated one, though it is DIN rail mount.
6) When should I use a molded case breaker instead of the Leviton LB290?
The Leviton LB290 is a standard branch circuit breaker for residential and light commercial panelboards. When the application is a 3-pole feeder or distribution position rather than a single-phase branch circuit, a molded case device is the different animal: the ABB A2N Series in the A2 Series and the ABB E150 Series thermal magnetic breaker are both 3-pole molded case breakers, and the Square D PowerPacT B is a thermal magnetic breaker in the PowerPacT B series. Those go where three phases and a bolt-in or unit-mount distribution position are involved; the plug-on Leviton goes in the load center.
7) How many spaces does the Leviton LB290 2-pole breaker take up in the panel?
Two adjacent full-size spaces, because it's a 2-pole device that has to straddle both bus legs to get 240V. Count your open positions before ordering: two single-pole slots side by side on the same side of the panel, not two anywhere. If you only have scattered singles free, you'll need to reorganize the panel or add a sub-panel.
8) I need a higher amperage than 90A in the same Leviton plug-on breaker. What do I order?
The Leviton LB series covers this without changing form factor. The LB290 is the 90-amp unit and the LB212 is the 125-amp unit, both ordered under the same 2-pole plug-on configuration, so the mounting into compatible panelboard bus bars is the same either way. Match the amperage to the branch circuit conductor sizing and order the corresponding part number.
9) I'm standardizing breakers across a portfolio of buildings, does the Leviton LB290 help with that?
It does if the panels are Leviton load centers. Keeping one plug-on breaker family across a property means maintenance carries a single spare on the truck and any tech can swap it without checking panel compatibility first. The LB2 series gives you 90A and 125A in the same 2-pole plug-on form, so the higher-load positions stay in the same family. Where a building runs a different panel brand, that building needs its own breaker line; plug-on breakers don't cross between manufacturers.
10) Is the Leviton LB290 suitable for new construction or only for replacements?
Both. It's specified for new panel builds and for straight breaker swaps in existing Leviton load centers, including panel upgrades and renovation work. Because it plugs on with no extra hardware, the replacement case is the same job as the new-install case: the breaker goes on the bus and the branch conductor lands on the lug.
