THKMA826500 - 500Amp Circuit Breaker

THKMA826500 - 500 Amp Circuit Breaker

The THKMA826500 is a 500-amp, 2-pole molded-case circuit breaker designed for use in your commercial and industrial power distribution systems. Featuring an interchangeable thermal magnetic trip unit and internal common trip mechanism, it provides protection against overloads and short circuits while maintaining compatibility with existing THKM8 installations. The bolt-on design allows for secure mounting, and load-side lugs are included for conductor termination.

With interrupting ratings of 65kA at 240VAC, 35kA at 480VAC, and 25kA at 600VAC, this breaker is suited for applications where higher fault-current capacity is required. It is also HACR rated, making it suitable for you to use in heating, air conditioning, and refrigeration equipment where applicable. Built for demanding electrical environments, the THKMA826500 is intended to provide dependable circuit protection and long service life when properly installed and maintained.
