C-mac® time relay type RT18 is particularly made for the control of star-delta contactors.
When the supply voltage is connected, the relay activates in position 1-4, and the time period starts.
At the end of the set delay, the relay switches to neutral centre position for approx. 100 msec. Then it switches to position 1-3 and stays in this position, until the supply voltage is interrupted.
