Siemens QJ3H200 Molded Case Circuit Breaker MCCB

The Siemens QJ3H200 Molded Case Circuit Breaker is a rugged, three-pole MCCB rated for 200 A and designed for 120/240 V AC service, delivering precise, factory‑calibrated protection for three‑phase feeders in commercial and light industrial panels. As part of the QJ family—an lineage that includes the former ITE and Gould brands—the device leverages Siemens’ low‑voltage protection technology and integrates cleanly with standard Siemens switchgear, panelboards, and distribution enclosures used in North American electrical systems. The QJ3H200 designation denotes a 3-pole, 200‑amp rating within the 120/240 V envelope, enabling compact protection for three‑phase circuits such as motors, conveyors, and processing equipment where space and reliability matter. Designed for straightforward installation in configured panels, this MCCB provides robust protection for feeders and branch circuits while offering compatibility with Siemens Industry protection and automation ecosystems, making it a practical choice for upgrade or new installations.
