THLC134040WL - 40Amp Circuit Breaker

THLC134040WL - 40 Amp Circuit Breaker

The THLC134040WL is a 40-amp, 3-pole Type THLC1 circuit breaker with a non-interchangeable trip unit and current-limiting design. This breaker is rated for 150kA at 480VAC and 200kA at 240VAC, making it suitable for your applications where high available fault current is present. The unit is supplied with both line-side and load-side lugs and is designed for installation in compatible electrical distribution equipment.

Current-limiting breakers are commonly used to help reduce the amount of fault current that passes through a system during a short circuit. The THLC134040WL provides overcurrent protection while maintaining the original form and fit required for equipment designed to accept Type THLC1 breakers. Its compact dimensions make it suitable for use in a variety of commercial and industrial power distribution applications.
