THJK426150WL - 150Amp Circuit Breaker

THJK426150WL - 150Amp Circuit Breaker

The THJK426150WL Circuit Breaker is a 150-amp, two-pole molded-case breaker for your compatible commercial and industrial electrical distribution systems. Part of the THJK4 breaker family, this Q-Line circuit breaker features a thermal-magnetic trip unit, internal common-trip operation, and included line-side and load-side lugs. Its interrupting ratings are 65kA at 240VAC, 35kA at 480VAC, and 25kA at 600VAC, giving maintenance professionals key electrical ratings to consider when matching an existing installation. With its cable-in/cable-out connection arrangement and HACR-rated classification, the THJK426150WL is a catalog-specific replacement option for electrical equipment that requires the same combination of amperage, pole count, physical configuration, and protective characteristics.
