Carlo Gavazzi RSE4812-B is a 3-phase soft starter for induction motors, designed to limit inrush current and smooth startup in industrial control panels. It operates from a 480 Vac supply with a rated current of 12 Aac and uses a dual control-voltage scheme: UC from 24–110 Vac or DC and 110–480 Vac, with an internal supply (Us) and 2-phase control. The module is DIN-rail mountable and includes an internal bypass, measuring 45 mm in width, 82 mm in height, and 102.5 mm in depth. Part of the RSE family, this model is intended for panel builders and technicians configuring reliable soft-start of 3-phase induction motors in automation environments.
