Breaking capacity hits 76 kA at 240 VAC, 53 kA at 415 VAC, 32 kA at 440 VAC, and 12 kA at 500 VAC — that 76 kA figure at 240 V means it handles high-fault utility feeds in North American panels, while the 53 kA at 415 V covers most European industrial distribution. At 76.2 mm wide, 130 mm tall, and 70 mm deep, this MCCB fits standard Siemens SENTRON mounting bases and busbar systems — the 70 mm depth is shallow enough for compact enclosures, but verify the busbar connection clearance for the TM210 terminals. Front IP40 protection means it's fine for dry indoor panels; no washdown rating, so keep it out of wet or dusty environments unless it's behind a sealed enclosure door. Power loss is 11 W max at rated load — negligible for a single breaker, but if you're packing a dozen of these in a small panel, that heat adds up and may drive ventilation requirements.","metaTitle":"Siemens 3VM1140-3ED32-0AA0 SENTRON MCCB, 40 A, 3-Pole, 76 kA","metaDescription":"Siemens SENTRON 3VM1140-3ED32-0AA0 molded case circuit breaker, 40 A, 3-pole, 76 kA at 240 VAC.
