THQD32175WL - 175Amp Circuit Breaker

THQD32175WL - 175 Amp Circuit Breaker

The THQD32175WL is a 175-amp, 3-pole molded-case circuit breaker designed for use in your commercial and industrial electrical distribution systems that require dependable overcurrent and short-circuit protection. As part of the widely used THQD Q-Line series, this breaker features an internal common trip mechanism that simultaneously disconnects all three poles when an overcurrent condition is detected, helping you to protect connected equipment and electrical infrastructure. The cable-in/cable-out lug-lug configuration includes both line-side and load-side lugs, simplifying installation while providing secure conductor termination points. Built for long-term service, the THQD32175WL is a practical replacement solution where matching form, fit, and electrical ratings are important for maintaining existing systems.
