THJK436225WL - 225Amp Circuit Breaker

THJK436225WL - 225 Amp Circuit Breaker

The GE THJK436225WL is a 225 Amp, 3-pole molded case circuit breaker designed for use in your commercial and industrial electrical distribution systems where dependable overcurrent and short-circuit protection is required. Part of the trusted THJK4 Q-Line series, this breaker features a thermal magnetic, non-interchangeable trip unit with internal common trip, helping to protect your connected equipment and conductors from overloads and fault conditions. Its cable-in/cable-out (lug-lug) configuration includes both line-side and load-side lugs, simplifying installation and replacement in compatible systems.

Built for applications requiring higher voltage capabilities, the THJK436225WL carries interrupting ratings of 25kA at 600VAC, 35kA at 480VAC, and 65kA at 240VAC, making it suitable for a wide range of power distribution environments. The breaker is also HACR rated, allowing use in heating, air conditioning, and refrigeration applications where equipment protection and code compliance are important. Designed with the durability expected from molded case circuit breakers, this unit offers a practical solution for maintaining existing electrical infrastructure and supporting ongoing system operation.
