The 125 A continuous rating on an IEC frame 160 body means this breaker is sized for motor branch circuits or feeder loads in the 60–100 kW range on a 400 V system, depending on the load duty. The TM120M thermal element provides inverse-time overload protection; the magnetic instantaneous element handles short circuits. The adjustable Ii range (5–15× In) lets you set the magnetic trip point between 625 A and 1875 A, which is the primary tool for coordinating with downstream contactors or soft starters. That coil drops the breaker open when control voltage falls below about 70% of rated — standard for safety circuits where a loss of control power must disconnect the load. The nut keeper kit is a mechanical aid for panel builders — it retains the terminal nuts during wiring, which saves time on a crowded DIN-rail assembly. The lifecycle stage for this order code is listed as current, meaning Siemens has not issued a phase-out notice or last-time-buy window for the 3VA1112-6MH32-0DH0 as of the latest data. That is the standard status for a production-line part that is still being manufactured and stocked through normal Siemens distribution channels. For a BOM line that requires this exact code — with the TM120M release, UVR, and auxiliary switch configuration — the part is specified into the design and available to order.","metaTitle":"Siemens 3VA1112-6MH32-0DH0 Circuit Breaker, 125A, 70kA @ 415","metaDescription":"Siemens 3VA1112-6MH32-0DH0 IEC frame 160 circuit breaker, 125A, 70kA breaking capacity @ 415V.
