THLC134150WL - 150Amp Circuit Breaker

THLC134150WL - 150 Amp Circuit Breaker

The THLC134150WL is a 150-amp, 3-pole current limiting circuit breaker designed to provide overcurrent protection for your commercial and industrial electrical distribution systems. Built with a non-interchangeable trip unit, this unfused breaker delivers consistent circuit protection while helping limit the damaging effects of short-circuit currents. Its current-limiting design can reduce thermal and mechanical stress on connected equipment during fault conditions, making it a practical choice for your applications where dependable protection is essential.

Featuring an interrupting capacity of 150kA at 480VAC and 200kA at 240VAC, the THLC134150WL is suited for installations requiring high fault-current protection. The breaker includes both line-side and load-side lugs, helping you to simplify installation and maintenance. Designed for form, fit, and functional compatibility within systems utilizing THLC1 series circuit breakers, this unit is built to last and supports the continued operation of existing electrical infrastructure.
