At 690 V the breaking capacity drops to 7.5 kA — still adequate for most 690 V motor branch circuits, but verify coordination if the fault current exceeds that level. ## Motor protection and auxiliary configuration Built for motor protection duty with phase-failure detection and an undervoltage release (UVR) integrated. The auxiliary switch block carries two auxiliary switches plus one trip-alarm switch (HP type), giving the PLC or safety relay a dedicated signal on fault — no extra wiring for a separate alarm contact.","metaTitle":"Siemens 3VA2325-7MN32-0BJ0 SENTRON MCCB, 250 A, 3-Pole, Moto","metaDescription":"Siemens SENTRON 3VA2325-7MN32-0BJ0 molded case circuit breaker, 250 A at 40-70°C, 3-pole, motor protection design with undervoltage release.
