Low power (under-voltage) will certainly damage any refrigeration appliance's compressor. the fridgeguard protects your appliance by disconnecting the power when it goes below unacceptable level. additionally, there is a delay when power returns to normal. this will ensure that the appliance is not switched on-off repeatedly during fluctuations nor is it subjected to a massive surge normally experienced when power returns after power cuts.
