Thermal derating is flat from 40 °C to 50 °C at 32 A, then drops only 1 A per 5 °C step through 70 °C. That means a panel running at 55 °C ambient still delivers 31 A — no need to oversize the frame for a warm enclosure. ## Mounting and integration — fits the standard DIN-rail footprint The breaker measures 70 mm deep by 76.2 mm wide by 130 mm high — a standard 3-pole MCCB footprint that clips onto a DIN rail or mounts directly to a backplate. At 76.2 mm wide, it occupies three modular 25.4 mm positions, so you can plan the gland plate and wireway fill before the panel arrives. Maximum power loss is 11 W, which is low enough that natural convection in a typical enclosure handles the heat without forced air.","metaTitle":"SENTRON 3VM1132-5EE32-0AA0 MCCB, 320 A, 3-Pole, TM220","metaDescription":"SENTRON 3VM1132-5EE32-0AA0 molded case circuit breaker, 3-pole, 320 A, TM220 release, 187 kA at 240 V.
