The Siemens SENTRON 3VA2325-7MN32-0AD0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed as the panel warms up. It's purpose-built for motor protection, with integrated phase failure detection that catches a lost leg before the winding takes the hit. The 330 kA interrupting rating at 240 V drops to 242 kA at 415/440 V and 187 kA at 500 V; at 690 V it still holds 7.5 kA, which covers most low-voltage distribution faults without cascading upstream. Three auxiliary switches (HQ type) are built in for status feedback to the PLC or DCS.
