Breaking capacity is the headline here: 76 kA at 240 V AC, 53 kA at 415 V, 32 kA at 440 V, and 12 kA at 500 V. For a 25 A frame, that's serious fault-interruption headroom — it'll clear a high-energy arc flash without upstream fuses having to open, which matters for selective coordination in a multi-level panel. This breaker holds 25 A from 40 °C all the way to 50 °C, then drops to 24 A at 55–60 °C, and 23 A at 65–70 °C. That's a shallow derating curve — you lose only 2 A over a 30 °C rise. In a packed panel where ambient hits 50 °C, you still get full 25 A. At 70 °C, you're at 23 A, which is still 92% of the base rating. Most MCCBs in this class start derating sooner. Maximum power loss is 9 W — low enough that you don't need to factor much heat into the enclosure's thermal budget, even with several breakers ganged together. ## Physical fit — panel integration notes The IP40 front means it's sealed against tools and fingers from the front, but the back and sides are open to the enclosure interior — typical for a panelboard install.","metaTitle":"Siemens 3VM1125-3ED32-0AA0 SENTRON MCCB, 25A, 3-Pole, 76kA@2","metaDescription":"Siemens SENTRON 3VM1125-3ED32-0AA0 molded case circuit breaker, 25A rated at 40°C, 3-pole, TM210 trip unit, 76kA@240V.
