The Siemens SENTRON 3VA2325-6HL32-0JA0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous current, designed for line protection in distribution panels and motor control centers.
This MCCB delivers 242 kA interrupting capacity at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V. The steep drop at 690 V means this breaker is not a good fit for 690 V line-side faults in high-available-fault-current scenarios — the 7.5 kA rating is the limiting figure for that voltage class. For typical 480 V or 400 V industrial distribution, the 187 kA rating is well above what most service-entrance panels will see, so it gives you headroom for high-fault installations.
Dimensions are 248 mm high, 138 mm wide, and 110 mm deep. The 138 mm width is the standard 3-pole MCCB footprint for this SENTRON frame size, so it will drop into existing panel cutouts and bus-bar arrangements designed for the 3VA2 series. Depth at 110 mm is shallow enough for most 400 mm deep enclosures without crowding the door clearance.
