Above that it starts to derate: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. If your panel sits near a hot motor or in a sun-baked cabinet, that 91 A at 70 °C is the number you size to, not the 100 A label. The maximum power loss is 25 W, so account for that heat in your enclosure thermal calculation. ## Footprint and panel fit The 4-pole width of 101.6 mm means it takes up about four 25 mm module spaces on a DIN rail — check your existing rail layout if you're swapping in a retrofit.","metaTitle":"Siemens 3VA1110-3EF46-0AA0 SENTRON MCCB, 100 A, 4-Pole, 240","metaDescription":"Siemens SENTRON 3VA1110-3EF46-0AA0 molded case circuit breaker, 100 A at 40 °C, 4-pole, 75.6 kA at 240 V.
