Siemens QJH23B200 Three Pole Circuit Breaker

The Siemens QJH23B200 is a Type QJH2 three-pole molded‑case circuit breaker rated for 200 A at 240 V AC, featuring a 22 kA interrupting capacity for three‑phase distribution. It uses a thermal‑magnetic trip mechanism with distinct long‑time and instantaneous trip actions to protect feeders against overloads and short circuits while minimizing nuisance trips. As part of Siemens’ QJ frame family, this 3‑pole MCCB is designed for installation in distribution panels in commercial or light industrial environments where 240 V systems require reliable overcurrent protection. The QJH23B200 is specified for 240 V operation and 200 A continuous current, making it a suitable choice for protecting circuits and feeders in 3‑phase 240 V electrical systems.
