Star Delta Timer

The Star Delta Timer is an essential component in industrial electrical systems, specifically used to control the starting sequence of electric motors. This timer facilitates the transition of a motor from a star (wye) configuration to a delta configuration, allowing for a smooth and controlled start-up process. By initially starting the motor in the star configuration, which reduces the starting current, and then switching to the delta configuration for full-speed operation, the timer helps minimize electrical stress and mechanical wear on the motor and associated equipment.
