What this MCCB delivers on the line side
The Siemens SENTRON 3VA2325-6HL32-0JC0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Breaking capacity runs 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V, so it handles high-fault utility feeds or transformer secondaries without cascading upstream. The frame is sized for line protection, not motor or generator duty.
Integration and auxiliary hardware
This variant ships with a factory-fitted shunt trip (STL) release and two auxiliary switches (HQ design), so it integrates directly into emergency-stop or remote-trip circuits without field wiring a separate undervoltage release. The basic switch supplied is 3VA2325-6HL32-0AA0. Dimensions are 248 mm high, 138 mm wide, 110 mm deep — fits standard MCCB panel cutouts for the SENTRON 3VA frame family.
