ABSTRACT:
A minimum off-time protection arrangement is disclosed for compressors, particularly refrigeration type compressors. A current transformer is placed in the circuit which controls the switching of the compressor and that current transformer provides a control signal to a minimum off-time circuit. The minimum off-time circuit prevents the compressor from being restarted for some minimum period of time after once being operated.
