TKMA826400WL **Older Style** - 400Amp Circuit Breaker

TKMA826400WL **Older Style** - 400 Amp Circuit Breaker

The TKMA826400WL molded case circuit breaker is a solid choice for your industrial and commercial electrical systems that need dependable overcurrent protection in existing power distribution equipment. Designed with an older style black face, this 2-pole, 400-amp breaker is often used as a direct replacement in legacy installations where matching the original form and fit is important. The cable-in/cable-out lug-lug configuration allows for straightforward installation, and both line- and load-side lugs are included to help reduce setup time in the field.

Built with an interchangeable thermal magnetic trip unit, the TKMA826400WL responds to overloads and short-circuit conditions to help protect connected equipment and electrical systems. Its internal common trip design allows both poles to trip together during fault conditions, helping maintain safe operation in demanding environments. The breaker is also HACR rated, making it suitable for heating, air conditioning, and refrigeration equipment applications. Designed for long service life in industrial settings, this TKM8 breaker continues to be widely used in facilities operating established electrical infrastructure.
