Undervoltage release (UVR) is integrated, so a loss of control voltage drops the breaker open — useful for emergency-stop chains or safety circuits that need a guaranteed disconnect on power loss. Thermal derating is published across the full operating range: it carries the full 250 A up to 50 °C ambient, then steps down to 240 A at 55 °C, 235 A at 60 °C, 230 A at 65 °C, and 225 A at 70 °C. The 3-pole footprint matches the standard SENTRON 3VA2 cutout, so a panel originally laid out for a 3VA2 MCCB accepts this unit without re-drilling or re-bussing. Maximum power loss is 40 W — worth noting for thermal calculations in a sealed enclosure. Latching endurance is 15 000 operations, which is typical for a motor-protection MCCB that sees occasional switching, not daily cycling.","metaTitle":"Siemens 3VA2325-7MN32-0BL0 SENTRON MCCB, 250 A, 330 kA at 24","metaDescription":"Siemens 3VA2325-7MN32-0BL0 SENTRON molded case circuit breaker, 250 A rated continuous current, 330 kA interrupting at 240 V.
