ABB CT-SAC.22 Star-Delta Electronic Timer Relay, Part Number 1SVR508210R0100, a compact and reliable industrial timing solution designed for three-phase motor starters, industrial automation panels, motor control centers (MCC), and electrical control applications.

The ABB CT-SAC.22 belongs to ABB's CT-C series of electronic time relays and features a dedicated star-delta timing function for controlling the starting sequence of three-phase induction motors.

The relay offers four selectable timing ranges covering 0.05 seconds to 10 minutes, allowing flexible adjustment of the motor's star-starting period. Its adjustable transition time of 20 milliseconds to 100 milliseconds provides a configurable interval between the star and delta switching operations, helping support coordinated motor starter control.
