Breaking capacity spans 52.5 kA at 240 V down to 7.5 kA at 690 V, so the SCCR coordination study needs to match the available fault current at the installed voltage. At 415 V it interrupts 32 kA; at 440 V, 13.6 kA. Full 25 A rating holds through 50 °C ambient; above that it derates linearly to 22.5 A at 70 °C. If the breaker shares a crowded enclosure with heat-generating devices, factor the actual ambient at the breaker inlet — not the room temperature — when sizing the load. The IP40 front protection means it's sealed against tools and small objects but not against dust ingress — suitable for clean indoor panels, not washdown areas. ## Auxiliary contacts and release options The auxiliary contacts signal breaker position (open/closed) to a PLC or status lamp; the alarm switch changes state only on a trip event, distinguishing a manual-off from a fault. The undervoltage release (UVR) is wired separately — if its coil loses power, the breaker opens. For frequent switching applications, check the electrical endurance curve in the device manual.","metaTitle":"Siemens 3VA1025-2ED32-0BH0 SENTRON MCCB, 25 A, 3-Pole, Line","metaDescription":"Siemens 3VA1025-2ED32-0BH0 SENTRON molded case circuit breaker, 25 A rated continuous current, 3-pole, line protection, TM210 release, undervoltage release, 52.5 kA at 240 V.
