Siemens SENTRON 3VA2325-7MN32-0DC0 — 250 A Motor Protection MCCB
The Siemens SENTRON 3VA2325-7MN32-0DC0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuously from 40 °C through 70 °C without derating — that flat thermal curve means it holds full ampacity in a warm enclosure where many breakers would need a down-rate. The interrupting capacity reaches 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 7.5 kA at 690 V — these numbers govern selectivity coordination downstream; at 415 V the 242 kA SCCR covers most industrial service-entrance and feeder applications without needing a current-limiting upstream device.
Panel footprint: 138 mm wide, 248 mm tall, 110 mm deep — fits standard SENTRON 3VA mounting plates and busbar systems. The basic switch core is order code 3VA2325-7MN32-0AA0; the -0DC0 suffix adds the factory-fitted undervoltage release and auxiliary switch block, so no field wiring of add-on modules is needed.
