LHL36350 - 350 Amp Circuit Breaker

LHL36350 - 350 Amp Circuit Breaker

A replacement breaker has to match the equipment in front of you—not just the amp number on the handle. The LHL36350 is a 350A, 3-pole molded case circuit breaker with a thermal-magnetic trip unit and unit-mount construction. It uses lugs at both ends, with line-side and load-side connections identified by the manufacturer under the AL400LA terminal configuration. Its electrical ratings include 25 kA at 600VAC and 50 kA at 250VDC, while the magnetic characteristics are listed at 1,750A hold current and 3,500A tripping current. For maintenance work on existing equipment, those details give you a much clearer compatibility picture than amperage alone.
