At 690 V the 17 kA rating still covers most industrial motor-control center bus faults, but the real strength is in the sub-480 V range. ## Thermal derating — what 125 A actually means at panel temperature At 55 °C it's 120 A, at 60 °C it's 117.5 A, at 65 °C it's 115 A, and at 70 °C it's 112.5 A. If your panel ambient runs 55 °C or higher, size the load side for the derated figure — the TM240 release won't trip early, but the continuous rating is what the thermal element is calibrated to. ## Integrated undervoltage release No auxiliary contact block is fitted (without), and there's no voltage trigger or communication function. The trip indicator is also absent, so you won't get a local flag; plan for a remote indication path if needed. The 76.2 mm width is a standard 3-pole MCCB footprint — it occupies three 25.4 mm (1-inch) module positions on a DIN rail or panel-mount plate.","metaTitle":"Siemens 3VA1112-6EF36-0BA0 SENTRON MCCB, 125 A, 220 kA at 24","metaDescription":"Siemens SENTRON 3VA1112-6EF36-0BA0 molded case circuit breaker, 125 A rated continuous current, 3-pole, TM240 release, 220 kA at 240 V.
