Siemens QRH22B175 Circuit Breaker – QR Series – 175A – 2 Pole – 240VAC – Bolt-On – Thermal Magnetic – 25kAIC

The Siemens QRH22B175 is a QR Series molded case circuit breaker designed for high-capacity branch and feeder protection in residential, commercial, and light industrial electrical systems. Rated at 175A and 240VAC, this 2-pole breaker provides a 25kA interrupting capacity at 240VAC, making it suitable for installations with higher available fault current levels.

This breaker utilizes a thermal-magnetic trip unit providing Long-Time and Instantaneous (LI) protection for reliable response to overload and short-circuit conditions. Its bolt-on design ensures a secure mechanical and electrical connection in compatible Siemens panelboards, while the non-interchangeable trip unit delivers factory-calibrated protection performance.
