Power semiconductor module for 3RW4465/4466 soft starters
The Siemens 3RW4766-0LC00 is a power semiconductor module rated 690 V and 1214 A, designed for use in 3RW4465/4466 soft starters — two units per device. This is not a standalone soft starter; it is the power stack module that handles the main motor current in the larger-frame 3RW44 series. The 1214 A rating at 690 V means it controls high-power motors in the 600–700 kW range, typical for large pumps, compressors, and conveyors in heavy industrial plants.
Sourced through authorized distribution channels against a BOM quantity.
