QDF32175TS - 175 Amp Circuit Breaker

QDF32175TS - 175 Amp Circuit Breaker

The QDF32175TS is a 3-pole, 175-amp thermal-magnetic circuit breaker designed to provide dependable overcurrent and short-circuit protection for 240 VAC electrical distribution systems. Featuring a 25 kA interrupting capacity at 240 VAC, this breaker helps protect electrical equipment and branch circuits in demanding commercial and industrial applications. Its non-interchangeable trip unit provides a fixed protective setting, helping maintain consistent system coordination and reducing the possibility of unauthorized trip modifications. Built with 1/4-20 inch studs on both the line and load sides, the QDF32175TS allows for secure cable terminations where stud-mounted connections are required. Whether you're replacing an existing breaker or maintaining critical electrical infrastructure, this thermal-magnetic breaker delivers the reliable performance and circuit protection that professionals expect.
