TKMA826300WL **Older Style** - 300Amp Circuit Breaker

TKMA826300WL **Older Style** - 300 Amp Circuit Breaker

The TKMA826300WL Older Style Black Face molded case circuit breaker is built for your commercial and industrial electrical systems that require dependable overcurrent protection and compatibility with existing equipment. This 2-pole, 300 amp breaker uses a thermal magnetic trip unit with internal common trip functionality to help protect connected systems from overloads and short circuits. Its cable-in/cable-out lug-lug design allows for secure wiring connections, and both line-side and load-side lugs are included for added installation convenience. The older style black face configuration makes it a practical replacement option for facilities maintaining legacy TKM8 equipment and existing panel setups.

Designed for demanding electrical applications, the TKMA826300WL offers interrupting ratings of 22k @ 600VAC, 30k @ 480VAC, and 42k @ 240VAC. It is also HACR rated, making it suitable for HVAC and refrigeration-related systems where reliable protection is important for day-to-day operation. Built to last and intended for long service life in industrial environments, this breaker is commonly found in manufacturing plants, commercial buildings, mechanical systems, and power distribution equipment.
