In a tightly packed panel — say a 40 °C internal ambient with a row of breakers side by side — you can load it to 40 A continuous without worrying about nuisance tripping. Max power loss is 14 W, which is modest for a 40 A frame; that helps keep the enclosure from cooking. The 3VM1040-3ED32-0AA0 measures 70 mm deep by 76.2 mm wide by 130 mm tall. The 76.2 mm width (3 inches) is a standard 3-pole MCCB footprint — it'll drop into a panel that was laid out for a 3-pole frame without re-drilling the backplate.","metaTitle":"Siemens 3VM1040-3ED32-0AA0 SENTRON MCCB, 40A, 3-Pole, TM210","metaDescription":"Siemens SENTRON 3VM1040-3ED32-0AA0 molded case circuit breaker, 40 A, 3-pole, TM210 release, 76 kA at 240 V.
