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.
