Siemens SENTRON 3VM1112-3ED32-0AA0 is a 3-pole MCCB from the 3VM1 frame series with a rated current of 125A and breaking capacity of 25kA at 415V AC. The breaker uses a TM210 thermal magnetic trip unit with fixed overload and fixed instantaneous short-circuit protection settings. Its compact frame size, robust protection characteristics, and high operational reliability make it suitable for low-voltage power distribution systems, machinery protection, motor feeders, and industrial switchboards.
The breaker comes with front-side connections and nut keeper kit terminals for secure installation and enhanced electrical connectivity
