That 40 A holds through 50 °C; at 65 °C it derates to 38 A, and at 70 °C to 37 A, so if the breaker lives in a hot panel near drives or transformers, check the ambient derate curve before sizing. The 121 kA breaking capacity at 240 V AC drops to 76 kA at 415 V, 53 kA at 440 V, and 12 kA at 500 V — that's the fault current it can safely interrupt at each voltage level without welding contacts. It's a straightforward thermal-magnetic breaker for feeder or branch circuit protection in a distribution panel. The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures.","metaTitle":"SENTRON 3VM1140-4ED32-0AA0 MCCB, 40 A, 3-Pole, TM210","metaDescription":"Siemens SENTRON 3VM1140-4ED32-0AA0 molded case circuit breaker, 40 A rated, 3-pole, TM210 thermal-magnetic trip.
