Description
Designed to safeguard commercial systems, the Square D LAP26400MB is a 2-pole, 400A molded case circuit breaker. It integrates into Square D switchboards and control panels. This legacy L-Frame breaker is built as a 2-pole device in a 3-pole housing. It is superseded by the PowerPacT L-Frame series, which requires a retrofit kit for mounting. Handling up to 600VAC, it offers a 30kAIC rating at 480V. The unit utilizes an adjustable magnetic trip system for precise LI protection.Specifications

Product FAQs
5 answersWhat is the difference between the Square D LAP26400MB and LAL26400MB?
The LAP26400MB features lugs on the OFF (load) side and terminal pads on the ON (line) side. The LAL26400MB is equipped with lugs on both the line and load sides. Both are 400A, 2-pole, L-frame circuit breakers with identical electrical ratings.
What does the MB suffix indicate on the LAP26400MB catalog number?
The MB suffix designates a short operating handle. This low-profile handle design ensures that panelboard and enclosure doors can close securely without interference.
What frame size is the LAP26400MB?
This breaker belongs to the Square D legacy L-Frame family. It shares the same physical dimensions and mounting footprint as other LAL, LHL, and LAP molded case circuit breakers.
What does unit mount mean for the LAP26400MB?
Unit mount indicates that this breaker is designed to be bolted directly to a backpan or mounting plate in a control panel or enclosure, rather than plugging into a busway system.
Does the LAP26400MB include a push-to-trip feature?
Yes, it includes a push-to-trip button on the faceplate. This allows you to manually trip the breaker mechanism to verify proper operation without exposing personnel to live parts.
