It's designed for starter protection — meaning it's tuned for motor branch circuits where the inrush and overload profile differs from a straight feeder breaker. Breaking capacity hits 187 kA at 240 V, 121 kA at 415 V, and 76 kA at 500 V, so it handles high-fault panels without cascading upstream. ## Current derating and thermal budget Above that, it derates: 245 A at 55 °C, 239 A at 60 °C, 234 A at 65 °C, and 228 A at 70 °C. Maximum power loss is 30 W, which matters for enclosure heat rise calculations — especially in a sealed panel with other heat sources. Current lifecycle stage per the manufacturer — no end-of-life notice on record.","metaTitle":"SENTRON 3VM1325-5MH32-0AA0 MCCB, 250 A, 3-Pole, 187 kA at 24","metaDescription":"SENTRON 3VM1325-5MH32-0AA0 molded case circuit breaker, 250 A continuous at 40 °C, 3-pole, 187 kA breaking at 240 V.
