Star-delta timing relay IP41 PT420-8 POWER ELECTRONICS

It is used in automation devices for starting high power motors, ensuring a smooth transition from star to delta connection.

In addition to the basic delay time between star and triangle, an intermediate blank transition time can be set to avoid magnetic coupling of the two relays.
