The 3-pole design with phase failure detection means it protects motors against single-phasing, and the four HQ auxiliary switches give you status feedback for PLC or HMI without adding external relays. ## Thermal derating and endurance — the numbers that govern real-world fit The 250 A rating holds flat from 40 °C through 50 °C, then derates to 240 A at 55 °C and 225 A at 70 °C. The 15 000 latching-endurance cycles (mechanical) tell you this breaker is built for switching duty, not just backup protection. ## Panel fit and mounting — what the dimensions tell you The 138 mm width, 248 mm height, and 110 mm depth fit the standard SENTRON 3VA2 panel footprint. Mounts via four-point screw fixing or optional DIN-rail adapter. No undervoltage release or ground-fault module fitted on this variant — those are add-on accessories if your application requires them.","metaTitle":"Siemens 3VA2325-7MN32-0AE0 SENTRON MCCB, 250A, 330kA at 240V","metaDescription":"Siemens 3VA2325-7MN32-0AE0 SENTRON molded case circuit breaker, 250A rated continuous current, 330kA breaking capacity at 240V.
