Breaking capacity is 76 kA at 240 V AC, 53 kA at 415 V, 32 kA at 440 V, and 12 kA at 500 V — so at typical 400 V distribution voltages it clears faults well above the 40 A frame rating, giving headroom for high-fault panels. The 70 mm depth × 101.6 mm width × 130 mm height footprint fits standard MCCB panel cutouts; front IP40 protection suits enclosed panel mounting where the breaker face is behind a door. Rated current holds at 40 A from 40 °C through 50 °C, then steps down to 39 A at 55–60 °C, 38 A at 65 °C, and 37 A at 70 °C — so in a warm panel (55 °C ambient) you lose 1 A per pole, not enough to force a frame upsizing for most loads. Maximum power loss is 11 W.","metaTitle":"Siemens SENTRON 3VM1140-3ED42-0AA0 MCCB, 40 A, 4-Pole, 76 kA","metaDescription":"Siemens SENTRON 3VM1140-3ED42-0AA0 molded case circuit breaker, 40 A, 4-pole, TM210 release, 76 kA at 240 V.
