That means you set the thermal pickup to match your load cable or transformer feeder, and the magnetic trip holds at 1250 A — no ground-fault module here, so this is a straight line-protection breaker for feeders or main incomers where GFCI is handled downstream. Rated continuous current holds at 125 A from 40 °C through 50 °C ambient, then derates to 122 A at 55 °C and 120 A at 60 °C. That 5 °C window between 50 °C and 55 °C is where a panel builder needs to check the internal enclosure temperature — if your cabinet runs hot from drives or transformers, the 3 A drop at 55 °C is small but real. At 70 °C it still carries 114 A, which is better than many MCCBs in this frame class. That IP40 is typical for switchboard mounting — it keeps tools and fingers out but isn't rated for washdown.","metaTitle":"Siemens 3VM1112-4EE36-0AA2 SENTRON MCCB, 125 A, 121 kA at 24","metaDescription":"Siemens SENTRON 3VM1112-4EE36-0AA2 molded case circuit breaker, 125 A rated, 121 kA at 240 V, 76 kA at 415 V. 3-pole, line protection.
