Low power (under-voltage) will certainly damage any refrigeration applianceâs compressor. The Mk Fridge Guard protects your appliance by disconnecting the power when it goes below unacceptable level or when the power goes off abruptly without warning when the fridge is on . Additionally, there is a delay when power returns to normal it takes few minutes. 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.
