TKMA826350 **Older Style** - 350Amp Circuit Breaker

TKMA826350 **Older Style** - 350 Amp Circuit Breaker

The TKMA826350 Older Style Black Face circuit breaker is designed for your industrial and commercial electrical systems that require dependable overcurrent protection and compatibility with existing equipment layouts. This 2-pole, 350-amp molded-case circuit breaker features an interchangeable thermal-magnetic trip unit that responds to both overload and short-circuit conditions. Its internal common trip mechanism allows both poles to trip together when protection is needed, helping support safer system operation. The bolt-on design provides a secure connection within compatible electrical distribution equipment, while the included load-side lugs simplify installation. Commonly used in existing power distribution systems, the TKMA826350 is a practical replacement solution for facilities maintaining legacy electrical infrastructure and equipment originally built around this breaker style.
