THKMA836350 - 350Amp Circuit Breaker

THKMA836350 - 350Amp Circuit Breaker

The THKMA836350 Circuit Breaker is a 350-amp, three-pole industrial molded-case breaker for your compatible commercial and industrial electrical distribution systems. With a THKM8 breaker configuration, bolt-on mounting, an interchangeable thermal-magnetic trip unit, and internal common-trip operation, this breaker provides the electrical and mechanical characteristics needed when evaluating a replacement for existing equipment. Its specified interrupting capacities are 65kA at 240VAC, 35kA at 480VAC, and 25kA at 600VAC. The THKMA836350 is also HACR-rated and includes load-side lugs, so terminal configuration is an important part of replacement planning.
