THLC234175WL - 175Amp Circuit Breaker

THLC234175WL - 175 Amp Circuit Breaker

The THLC234175WL is a 175-amp, 3-pole THLC2 circuit breaker built for reliable protection in your commercial and industrial electrical systems. With a non-interchangeable trip unit and unfused, current-limiting design, it helps you safeguard equipment from overcurrent situations while maintaining system integrity. Rated at 150kA @ 480VAC and 200kA @ 240VAC, it can handle high fault currents where a strong interruption capacity is needed. It comes with line-side and load-side lugs for easier installation and fits seamlessly into existing THLC2 breaker setups. Designed for long-term use, it’s a practical solution for keeping older electrical systems functioning safely.
