panel-mount time relay / for contactors
Timing relay for star-delta switches
4 time ranges from 0,4 sec. to 10 min.
Time adjustment on built-in potentiometer
1-pole relay output with neutral centre position
100 msec. fixed neutral time
Phase-neutral or phase-phase supply voltage
Made in accordance with the CE and EMC regulations
The 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.
