High Quality Siemens QRH22B100 – 100A 2 Pole Molded Case Circuit Breaker

Engineered for high interrupting capacity, the Siemens QRH22B100 is a 2-pole, 100A MCCB. It utilizes a thermal-magnetic trip unit for long-time and instantaneous (LI) protection in commercial systems. This bolt-on breaker mounts into Siemens P2, P3, P4, and P5 panelboards, and SB switchboards. It serves as a direct replacement for legacy QJ22B100 and QJH22B100 breakers. Rated at 25kAIC at 240VAC, it includes a push-to-trip mechanism and supports reverse feed applications.
