THKMA836600WL - 600Amp Circuit Breaker

THKMA836600WL - 600 Amp Circuit Breaker

The THKMA836600WL is a 600 Amp, 3-pole molded case circuit breaker designed for use in your commercial and industrial electrical distribution systems requiring dependable overcurrent and short-circuit protection. Built on the THKM8 platform, this breaker features an interchangeable thermal magnetic trip unit with internal common trip operation, helping to protect your connected equipment and conductors by disconnecting all poles during an overcurrent or fault condition.

Configured as a cable-in/cable-out (lug-lug) breaker, the THKMA836600WL includes both line-side and load-side lugs, simplifying installation in a variety of switchboards, panelboards, and distribution equipment. Its HACR rating makes it suitable for heating, air conditioning, and refrigeration applications where properly rated circuit protection is required. Designed for demanding electrical environments, this breaker provides the form, fit, and functional characteristics needed for maintaining and servicing existing power distribution systems. Like many industrial molded case breakers of its class, it was built for long-term service and dependable operation when properly installed and maintained.
