LHL36250 - 250 Amp Circuit Breaker

LHL36250 - 250 Amp Circuit Breaker

The LHL36250 is very specific: a 250A, 3-pole molded-case circuit breaker with a thermal-magnetic trip unit, unit-mount construction, and lug connections on both ends. That combination matters when you're working on existing equipment. The line side uses lugs. So does the load side. The terminal identifier is AL400LA, and the breaker measures approximately 11 inches high by 6 inches wide by 5.84 inches deep. Electrically, the manufacturer's specifications list an interrupting rating of 25 kA at 600VAC and 50 kA at 250VDC. Its magnetic characteristics are listed at 1,250A hold current and 2,500A tripping current.

Material Compliance and Certifications

The supplied manufacturer information identifies the LHL36250 as UL Listed and lists CSA and IEC certifications. The manufacturer description also identifies the LH breaker family as certified to UL 489, CSA, and IEC requirements.

Where It Works Best

The LHL36250 250A 3-pole circuit breaker is a particularly relevant match for existing or legacy electrical distribution equipment that requires an LH unit-mount breaker with lug connections on both sides.

When you're trying to identify an LHL36250 replacement circuit breaker, that's the practical way to approach it. Match the catalog number, 250A rating, three poles, thermal-magnetic trip, unit-mount construction, AL400LA terminals, line and load lugs, interrupting ratings, magnetic characteristics, and physical dimensions. When those specifications correspond to the existing equipment, the LHL36250 can be evaluated for the required form, fit, and function.
