What the interrupting ratings mean for your panel
The Siemens SENTRON 3VA2225-6JP32-0KC0 is a 3-pole molded case circuit breaker rated for 250 A continuous at 40 °C, with a thermal derating curve that holds 250 A up to 50 °C and drops to 200 A at 70 °C — so in a warm enclosure you size for the actual ambient, not the nameplate. The interrupting ratings are what decide whether this breaker clears a fault without welding its contacts or venting arc gas: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 4.5 kA at 690 V. That spread means the breaker is designed for high-fault-current 480 V and 600 V class panels where the available fault current can exceed 100 kA; at 690 V the interrupting capacity drops sharply, so verify the SCCR at that voltage before specifying it for 690 V switchgear.
Built-in accessories and panel fit
This variant ships with a shunt trip (STL) release and two HQ auxiliary switches — no undervoltage release, no ground-fault monitoring. The communication function is present, so it can report status or accept remote trip commands over the SENTRON bus. Dimensions are 105 mm wide, 181 mm high, 86 mm deep; it mounts on a DIN rail or direct panel, and the 3-pole footprint matches the standard SENTRON 3VA223 frame. The 86 mm depth is shallow enough to fit a 200 mm deep enclosure with room for wiring behind the breaker.
