The 690 V rating (7.5 kA) is lower but still sufficient for most 690 V distribution boards where the available fault current is typically under 10 kA. ## Motor protection and auxiliary layout Built-in phase failure detection means the breaker trips on loss of one phase — critical for a motor load because a single-phased motor draws locked-rotor current on the remaining phases and burns out fast. No separate phase-loss relay needed in the panel; the MCCB handles it internally. That gives remote trip capability and status feedback — useful for an E-stop chain or a PLC-driven shutdown sequence where you need to know the breaker tripped vs. being manually opened. The shunt trip also lets you integrate the MCCB into a safety circuit without adding an external contactor. Physical footprint: 138 mm wide, 248 mm tall, 110 mm deep. The 110 mm depth includes the rear arc chamber, so verify gland-plate clearance if the panel is shallow. ## Environmental and operating range The flat 250 A derating across the full operating range (–) means this breaker can sit in a non-air-conditioned panel in a Middle East plant or a freezer warehouse without needing a higher-rated frame. Maximum power loss is 37.5 W — plan for that heat in a sealed enclosure.","metaTitle":"Siemens 3VA2325-7MN32-0HH0 SENTRON MCCB, 250A, 3-Pole, Motor","metaDescription":"Siemens SENTRON 3VA2325-7MN32-0HH0 molded case circuit breaker, 250 A, 3-pole, motor protection design with phase failure detection, 330 kA at 240 V.
