Siemens QRH22B125 Circuit Breaker – QR Series – 125A – 2 Pole – 240VAC – Bolt-On – Thermal Magnetic – 25kAIC

The Siemens QRH22B125 is a QR Series molded case circuit breaker designed for reliable overcurrent protection in residential, commercial, and light industrial electrical systems. Rated at 125A and 240VAC, this 2-pole breaker provides a high interrupting capacity of 25kA at 240VAC, making it suitable for applications with elevated available fault currents.

Built with a thermal-magnetic trip unit, the QRH22B125 delivers Long-Time and Instantaneous (LI) protection against overloads and short circuits. Its bolt-on mounting design ensures a secure connection in compatible Siemens panelboards and distribution equipment, while the non-interchangeable trip unit enhances reliability and safety in fixed protection applications.
