Product details

The SENTRON 3VM1325-5MH32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous at 40 °C, with a TM120M thermal-magnetic release. 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.

Frequently asked questions

Will 3VM1325-5MH32-0AA0 drop into a panel specified around 3VA1112-5EE32-0AA0?

The 3VM1325 is a different frame series from the 3VA — same SENTRON family but different footprint and release options. Check the mounting pattern and bus-bar spacing before assuming a drop-in swap; the 3VM is a starter-protection design while the 3VA series includes more variants with electronic releases.
