Siemens QJH23B200S01 Molded Case Circuit Breaker

Siemens QJH23B200S01 Molded Case Circuit Breaker is a 200 A, 240 V AC three‑pole protective device in the Siemens QJH2 family of low‑voltage molded‑case circuit breakers. It protects distribution circuits in commercial and light‑industrial panels by providing thermal‑magnetic protection against overloads and short circuits and by interrupting fault currents to safeguard conductors and equipment. As part of the QJ frame lineage, the unit is intended for Siemens‑compatible MCCB installations, following standard mounting and wiring practices used with QJ‑series devices. The 200 A, 240 V rating denotes the maximum operating parameters for typical distribution applications; the exact interrupt rating (in kA) and any optional accessories or trip configurations are specified in regional Siemens product literature and catalogs. This model is suitable for mains and feeder protection in panels, switchgear, and load centers where a 3‑pole MCCB is required. For precise compatibility with your panel and to confirm listings and available accessories for the QJH2 line, consult the official Siemens MCCB documentation or contact an authorized Siemens distributor.
