Product FAQs
8 answersCan I use the LAP36250MB to replace an older LAL or LHL circuit breaker?
Yes, the LAP36250MB serves as a direct drop-in replacement for older Square D LAL and LHL frame breakers with matching specifications.
What does the MB suffix indicate on the LAP36250MB catalog number?
The MB suffix designates a short operating handle. This shorter lever ensures that panel doors can close properly in specific Square D switchboards and control panels where clearance is limited.
What wire sizes are accepted by the lugs on this 250A breaker?
The factory-installed lugs accept either a single 1 AWG to 600 kcmil aluminum or copper wire, or two 1 AWG to 250 kcmil wires per phase.
Is the LAP36250MB suitable for heating, air conditioning, and refrigeration equipment?
Yes, this breaker is HACR rated, making it approved for use with commercial HVAC and refrigeration motor loads.
Does this L-Frame breaker include a visual trip indicator?
Yes, it features a Visi-Trip indicator that provides clear visual confirmation when the breaker has tripped due to an overcurrent or short circuit fault.
Can this molded case circuit breaker be used in DC applications?
Yes, the LAP36250MB is rated for up to 250VDC with an interrupting capacity of 10 kAIC, making it suitable for specific direct current control panels and distribution systems.
How does the LAP36250MB mount inside the panel?
This is a unit-mount, bolt-on circuit breaker. It secures directly to the chassis or backpan of Square D switchboards and motor control centers rather than plugging onto a busbar.
