For Refrigerators, Freezers, Water Coolers or any Appliance with a Max Current of 10 Amps. Protect your appliance from HIGH Voltage (140 VAC) or LOW voltage (90 VAC) by interrupting the current flow. Once the voltage returns to normal, the wait signal will on for 3 minutes. After this period, the NORMAL light will turn on which will allow the current to flow.
