THLC434350WL - 350Amp Circuit Breaker Description
THLC434350WL - 350 Amp Circuit Breaker
The THLC434350WL is a 350-amp, 3-pole current limiting circuit breaker designed for use in your commercial and industrial power distribution systems. Featuring a fixed, non-interchangeable trip unit and an unfused design, this breaker provides overcurrent protection for circuits where high fault current levels may be present. It comes equipped with both line-side and load-side lugs, helping you to simplify installation in compatible equipment. With an interrupting capacity of 150kA at 480VAC and 200kA at 240VAC, the THLC434350WL is intended for applications that require substantial short-circuit protection. Its current limiting design helps you reduce the amount of energy that passes through the system during fault conditions. Built for long-term service, this breaker is often used as a direct replacement in existing electrical distribution equipment where matching ratings and physical compatibility are important.
