TKMA826600WL **Older Style** - 600Amp Circuit Breaker

TKMA826600WL **Older Style** - 600 Amp Circuit Breaker

The TKMA826600WL molded case circuit breaker is a 2-pole, 600-amp industrial circuit breaker designed for you to use in electrical distribution systems requiring dependable overcurrent and short-circuit protection. Featuring the older-style black-face configuration, this breaker is well-suited for maintaining compatibility with existing installations where matching form, fit, and function are important. Built with an interchangeable thermal magnetic trip unit and internal common trip mechanism, the TKMA826600WL helps you protect electrical equipment and conductors from overloads and fault conditions while supporting safe system operation.

Configured as a cable-in/cable-out (lug-lug) breaker, this unit features both line-side and load-side lugs for ease of installation. Its thermal magnetic trip design provides a reliable response to both sustained overloads and instantaneous fault currents, making it suitable for a wide range of commercial and industrial power distribution applications. Designed for demanding environments, these circuit breakers were built to last and remain a practical solution for maintaining existing electrical systems.
