The ABB 1SFB476030D1001 is an industrial‑grade control power transformer designed to supply a stable low‑voltage control circuit from a higher primary power source. This type of transformer is typically used inside motor control centers, soft starter panels, drive systems, automation cabinets, and other electrical control assemblies to provide a reliable supply for control circuitry, relays, contactor coils, logic I/O, meters, and auxiliary devices.
