Maximum power loss is 75 W, which should be factored into enclosure thermal calculations, especially when multiple breakers are ganged. ## Environmental and electrical ratings Rated continuous current holds at 40 A from 40 °C through 50 °C ambient, then derates to 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C. No auxiliary contacts or ground-fault monitoring are integrated on this variant.","metaTitle":"Siemens 3VA2140-5MN32-0KA0 SENTRON MCCB, 40 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA2140-5MN32-0KA0 molded case circuit breaker, 40 A, 3-pole, ETU350M trip unit, motor protection version, 187 kA at 240 V.
