That's a shallow derate curve, so you don't lose much capacity in a warm enclosure. Breaking capacity is the headline: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 8.5 kA at 690 V. At 415 V — common for industrial three-phase — that 154 kA gives you serious fault-current headroom. ## DIN-rail fit and panel integration That's a standard SENTRON 3VA form factor — it clips onto the DIN rail and leaves room for side-by-side mounting with other 3VA breakers. The IP40 front rating means it's fine inside a closed panel; no washdown rating, so don't put it on the outside of a food-grade cabinet. Starter-protection variant with TM120M release and auxiliary contacts. Footprint 130 × 76.2 × 70 mm matches 3VA1112 frame. Verify trip unit before replacing a 3VA1112-5EF32-0CA0. ## Operating range and storage limits Rated insulation voltage 800 V, max DC operational voltage 500 V. Latching endurance 15,000 cycles.","metaTitle":"Siemens 3VA1112-6MH36-0AF0 SENTRON MCCB, 125 A, 220 kA at 24","metaDescription":"Siemens SENTRON 3VA1112-6MH36-0AF0 molded case circuit breaker, 125 A rated continuous, 220 kA breaking at 240 V. 3-pole, TM120M release, 1 aux + 1 trip alarm.
