Schiele 2.550.207.41 Star-delta timer

The star-delta timer, also known as star-delta starter timer or motor start relay, from Schiele with type number 2.550.207.41 is a mechanical timer for controlling the start-up of electric motors. It has the dimensions 9 x 3 x 11 cm and weighs 0.07 kg. Star-delta timers are used to gently start large three-phase asynchronous motors by a time-delayed switching from star to delta connection, thereby reducing the starting current. This model offers an adjustment range from 0.3s to 30s. Typical applications are found in industrial automation, in mechanical engineering for controlling conveyor systems or in pump and fan systems where a reduced starting current is required.
