THLC134040 - 40Amp Circuit Breaker

THLC134040 - 40 Amp Circuit Breaker

The THLC134040 is a 40-amp, 3-pole current-limiting circuit breaker designed for use in your electrical distribution systems that require dependable overcurrent protection and high interrupting capacity. Built with a non-interchangeable trip unit, this unfused breaker helps you to protect conductors and connected equipment from overloads and short circuits while maintaining consistent trip characteristics. Its current-limiting design helps reduce the amount of fault energy that passes through the electrical system during short-circuit events, thereby protecting downstream equipment. Engineered for applications requiring high fault-current ratings, the THLC134040 features interrupting capacities of 150 kA at 480 VAC and 200 kA at 240 VAC. The breaker includes load-side lugs for simplified installation and is housed in a compact footprint suitable for a variety of commercial and industrial power distribution environments. Built to last and designed to provide dependable circuit protection, this breaker serves as a form, fit, and functional replacement for compatible Type THLC1 applications.
