THLC134050 - 50Amp Circuit Breaker

THLC134050 - 50 Amp Circuit Breaker

The THLC134050 is a 50-amp, 3-pole current-limiting circuit breaker used in your commercial and industrial power distribution systems where high fault-current protection is required. Built with a non-interchangeable trip unit and an unfused design, this breaker helps provide consistent overcurrent protection while limiting the energy released during short-circuit conditions.

With interrupting ratings of 150kA at 480VAC and 200kA at 240VAC, the THLC134050 is intended for applications where available fault current levels demand a breaker capable of handling substantial interruption requirements. The breaker includes load-side lugs and is designed to fit compatible equipment utilizing the THLC1 frame.

Whether you installed in switchgear, distribution equipment, or other three-phase electrical systems, the THLC134050 delivers the form, fit, and function needed to keep existing equipment operating as intended. Its durable construction reflects the long service life expected from this style of circuit protection equipment and makes it a practical choice when maintaining established electrical infrastructure.
