Rated Icu = 70 kA at 415 V AC, which is the maximum short-circuit current it can safely interrupt without damage at that voltage — class H breaking capacity, so it handles high prospective fault levels common in industrial distribution panels. The short-circuit release (Ii) is adjustable between 5 and 15 times In. ## Deployment context Mounts on a DIN rail or panel base inside a standard industrial enclosure; the clamp-type terminals accept copper or aluminum conductors up to the frame rating, and the two built-in auxiliary switches (HP type) provide status feedback to a PLC or indication panel without needing an external accessory block.","metaTitle":"Siemens 3VA1112-6MH36-0AB0 Circuit Breaker, 70kA @ 415V, 125","metaDescription":"Siemens 3VA1112-6MH36-0AB0 IEC frame 160 MCCB, 70kA breaking capacity at 415V, 3-pole, 125A rated current, TM120M trip unit.
