Holiday Sale Siemens QJH23B100 – 100A 3 Pole Molded Case Circuit Breaker

Engineered for commercial distribution, the Siemens QJH23B100 delivers reliable thermal-magnetic protection in a 3-pole, 100A molded case package. This bolt-on MCCB installs into Siemens P1 through P5 panelboards and switchboards. As a legacy QJ frame device, it is often replaced by the newer QRH23B100, which requires a QR strap kit for retrofitting into existing enclosures. It features a 22kAIC interrupting rating at 240VAC, non-interchangeable trip, and a trip-free mechanism.
