The 3VA1112-6EF36-0AB0 delivers 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. This steep derating above 440 V is typical for MCCBs with a fixed TM release — the arc extinction capability drops as voltage rises. For a 480 V panel, the 75.6 kA figure still covers most industrial service-entrance and feeder applications, but at 690 V the 17 kA limit means it's suited only for low-fault sub-distribution or motor branch circuits with known short-circuit current. Rated 125 A from 40 °C up to 50 °C, then derates to 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. Maximum power loss is 28.1 W, which matters for enclosure heat-rise calculations when multiple breakers are ganged. The 3VA1112-6EF36-0AB0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. Depth of 70 mm is compact enough for shallow enclosures but leaves room for rear-connected busbars or cable lugs.","metaTitle":"3VA1112-6EF36-0AB0 SENTRON MCCB, 125 A, 220 kA at 240 V","metaDescription":"Siemens SENTRON 3VA1112-6EF36-0AB0 molded case circuit breaker, 3-pole, 125 A (40 °C), 220 kA at 240 V.
