GIZZU Voltage Protector 16A - Surge & Over/Under Voltage Protection for Home Appliances

Power fluctuations can destroy your valuable appliances in seconds. A sudden spike from a lightning strike, a brownout when the grid strains, or a surge when power returns after load shedding can fry a refrigerator compressor, a TV power supply, or a washing machine control board. The GIZZU Voltage Protector 16A sits between your wall socket and your appliance, monitoring the voltage continuously and disconnecting power instantly when it goes outside safe limits. It then waits for the voltage to stabilise before reconnecting, so your equipment never sees a harmful condition.

Who is it for

Anyone with appliances that are expensive to repair or replace. This protector is ideal for refrigerators, freezers, televisions, desktop computers, washing machines, and other motor-driven or electronic devices. It is especially useful in areas with frequent load shedding, unstable grid voltage, or overhead power lines exposed to storms. If you have ever lost a fridge after a power outage, this device is your insurance.

Main features

• Disconnects power when voltage drops below 170V or rises above 260V, protecting against brownouts and over-voltage.
• Built-in surge protection absorbs spikes caused by lightning or switching, preventing damage to sensitive electronics.
• Automatic reset with a 30-second delay after voltage returns to normal, so your appliance is not repeatedly switched on and off during unstable periods.
• Clear LED indicators show power status, waiting period, normal operation, and over/under voltage fault.
• Rated for 16A and up to 3680W, suitable for most household appliances on a standard 230V circuit.
• Fire-retardant PC housing and robust South African 3-pin plug and socket (Type M) for safe, local use.

Tips

Plug the voltage protector directly into a wall socket, not into an extension cord or multi-plug, to ensure proper earthing and maximum protection. Connect only one appliance per protector unless the total load is well under 16A. If the protector trips frequently, have an electrician check your supply voltage; it may be consistently too high or too low. The protector does not regulate voltage—it only disconnects—so for brownouts you may need a voltage stabiliser in addition to this device.
