THKMA826600 - 600Amp Circuit Breaker

THKMA826600 - 600 Amp Circuit Breaker

The THKMA826600 is a 600-amp, 2-pole molded case circuit breaker designed for use in your commercial and industrial electrical distribution systems where dependable overcurrent and short-circuit protection is required. Built with a thermal magnetic trip unit and internal common trip mechanism, this breaker helps you to protect conductors and equipment by responding to both sustained overload conditions and sudden fault currents. Its interchangeable trip unit design allows for maintenance flexibility while maintaining compatibility with applicable THKM8 breaker assemblies.

This bolt-on circuit breaker includes load-side lugs for secure conductor termination and is HACR rated, making it suitable for heating, air conditioning, and refrigeration applications where permitted by code and system requirements. With interrupting ratings of 25kA at 600VAC, 35kA at 480VAC, and 65kA at 240VAC, the THKMA826600 is engineered for demanding power distribution environments. Built to last and designed for long-term service, it provides a form, fit, and functional solution for maintaining and supporting existing electrical systems.
