Fridge Guard + TV Guard
Low power (under-voltage) will certainly damage any refrigeration and Television appliances. The fridge and TV guard protect 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.
