THLC134080WL - 80Amp Circuit Breaker

THLC134080WL - 80 Amp Circuit Breaker

The THLC134080WL is an 80-amp, 3-pole current limiting circuit breaker designed for use in your commercial and industrial electrical distribution systems where dependable overcurrent protection is required. As part of the THLC1 series, this unfused circuit breaker features a non-interchangeable trip unit and is built to help protect your electrical equipment and conductors from damage caused by overloads and short circuits. With interrupting ratings of 150kA at 480VAC and 200kA at 240VAC, it is well-suited for installations where high fault current capacity is an important consideration. This breaker includes both line-side and load-side lugs, helping simplify installation and conductor termination. Its current-limiting design helps you to reduce the amount of fault energy that reaches downstream equipment during short-circuit events. Built for long service life in demanding electrical environments, the THLC134080WL is commonly used in switchboards, panelboards, motor control systems, and other power distribution applications requiring an 80A, 3-pole circuit breaker with high interrupting capability.
