TKMA826500WL - 500Amp Circuit Breaker

TKMA826500WL - 500 Amp Circuit Breaker

The TKMA826500WL is a 2-pole molded case circuit breaker designed for your commercial and industrial electrical systems that require 500 amp overcurrent protection. It features a thermal magnetic trip unit with internal common trip operation to help you protect equipment and connected circuits from overloads and short circuits. The breaker uses a cable-in/cable-out lug-lug configuration and includes both line- and load-side lugs for installation in compatible equipment. This TKM8 breaker is commonly found in power distribution systems, HVAC equipment, and industrial applications where matching frame size, amperage, and interrupting ratings are important. Its HACR rating makes it suitable for heating, air conditioning, and refrigeration systems. Built for long-term service, the TKMA826500WL is often used in existing installations requiring a compatible replacement breaker with the same electrical characteristics and mounting style.
