Low power (under-voltage) will certainly damage any refrigeration applianceâs compressor. This Fridge Guard 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. Protect your appliances to avoid losses in the damaged refrigerator that will cause more expenses to replace. Order this Fridge guard with Jamboshop and delivery will be done within 3-5 days.
