THLC134020 - 20Amp Circuit Breaker

THLC134020 - 20 Amp Circuit Breaker

The THLC134020 is a 3-pole, 20-amp current limiting circuit breaker designed for use in your electrical distribution systems where dependable overcurrent protection and high interrupting capacity are required. Built with a non-interchangeable trip unit, this unfused circuit breaker helps you to protect equipment and electrical circuits from damage caused by overloads and short circuits. Its current-limiting design reduces the amount of fault energy that passes through the system during fault conditions, helping protect connected components.

Featuring interrupting capacities of 150 kA at 480 VAC and 200 kA at 240 VAC, the THLC134020 is well-suited for applications where high fault current levels may be present. The breaker includes load-side lugs for straightforward installation and secure conductor termination. Designed for long service life and dependable operation, this breaker is commonly used in commercial and industrial electrical systems requiring a compact, high-capacity protective device.
