What this MCCB carries and where it fits
The Siemens 3VA2225-6JP32-0HC0 is a SENTRON molded case circuit breaker rated for 250 A continuous current (Iu) with a breaking capacity of 242 kA at 240 V AC — enough to handle high-fault utility feeds or large transformer secondaries without cascading upstream. The 3-pole frame is sized for line protection, not motor or generator duty, so you are buying a feeder breaker, not a starter disconnect. The ETU550 electronic trip unit gives adjustable long-time, short-time, and instantaneous protection curves, plus ground-fault alarm or trip if you add the optional module. The shunt trip (STL) and two HQ auxiliary switches are factory-fitted, so the breaker arrives ready for remote tripping and status feedback — no field-wiring extra blocks. In a cement plant control room or a kiln MCC, the 48 W maximum power loss at full load means the heat stays inside the enclosure; plan your ventilation or derating accordingly. The breaker is rated for ambient operation from -25 °C to 70 °C, so it survives the summer heat next to a preheater without false trips.
Dimensions and panel fit
The 3VA2225-6JP32-0HC0 measures 105 mm wide, 181 mm high, and 86 mm deep — a standard SENTRON 3VA2 frame that drops into most existing MCC buckets or panel cutouts without re-drilling. The 86 mm depth leaves clearance for rear-mounted busbars or wiring troughs in a 400 mm deep enclosure.
