THLC134030 - 30Amp Circuit Breaker

THLC134030 - 30 Amp Circuit Breaker

The THLC134030 is a 30-amp, 3-pole current-limiting circuit breaker designed for use in your commercial and industrial power distribution systems that require dependable overcurrent protection and high interrupting capacity. Built with a non-interchangeable trip unit, this unfused breaker provides consistent protection while helping safeguard connected equipment from overloads and short circuits. Its current-limiting design helps reduce the fault energy that passes through the system during a short-circuit event, making it a practical solution for applications where fault-current management is critical. Engineered as a Type THLC1 circuit breaker, the THLC134030 features a compact footprint and includes load-side lugs for installation convenience. With interrupting ratings of 150kA at 480VAC and 200kA at 240VAC, it is well suited for electrical systems where high available fault current levels require a breaker with substantial interrupting capability. Built to withstand demanding operating environments, this circuit breaker is intended to provide long service life while maintaining proper form, fit, and function within compatible equipment.
