Star-Delta Starter with Two Timers PELC-PT429-8 pin. It is used in automation systems for starting three-phase asynchronous motors. It provides contacts for the direct activation of the star, delta, and main relay.

Additionally, it has contacts for direct connection of the start and stop buttons, as well as the automatic operation switch, thus replacing the entire electrical automation for starting. It operates as a regular time delay for the transition from star to delta after command from the buttons or the Automatic operation switch.

It also introduces a time of 20-300 ms (Transition time) between the operation of the star and delta. This avoids magnetic coupling of the power relays during transition and ensures their non-simultaneous activation.
