Hey.
Basically, No Volt Release Coli ensures that whenever supply resumes after switching off or supply failure, the motor does not start on it’s own, but starts only after the user starts it and that too through current limiting resistors.
The starter introduces large resistance initially and as the speed picks up, starter knob is turned forward in few steps. In last step, the resistance is bypassed. No volt coil retains the starter knob in last step it, as far as the supply voltage is available. When supply voltage fails, the knob returns to off position.
Thanks.
