The 40 A rating holds from 40 °C up through 50 °C, then derates to 37 A at 70 °C, so in a warm enclosure you lose about 3 A off the top. This breaker carries 53 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 500 V. The 7.5 kA at 500 V is lower, so if you're feeding a 500 V motor control center, verify your SCCR doesn't exceed that. The 101.6 mm width is a standard 4-inch footprint for a 4-pole MCCB, so it drops into most panel layouts without re-spacing. Front protection is IP40 — fine for a dry indoor enclosure, not for washdown areas. Maximum power loss is 14 W, which matters for thermal calculations inside a sealed cabinet. ## Release and accessories It's a workhorse for straightforward line protection. There's no communication function, no motor drive option, and no ground-fault monitoring built in. If you need those, you'd step up to the 3VA series with electronic trips and add-on modules.","metaTitle":"SENTRON 3VM1040-2ED42-0AA0 40A 4-Pole MCCB, 53 kA at 240 V","metaDescription":"SENTRON 3VM1040-2ED42-0AA0 molded case circuit breaker, 40 A rated, 4-pole, TM210 release.
