Low power (under-voltage) will certainly damage any refrigeration appliance's compressor. The Fridge Safe SF-A009F protects your appliance by disconnecting the power when it goes below unacceptable level. Additionally, there is a 3-minute 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.
