CNAODUN Refrigerator Surge Protector – 2 Pack, 120V 15A, Brownout and Overvoltage Protection

Protect what powers your home

The CNAODUN Refrigerator Surge Protector is a practical 2-pack solution built for single outlet protection on 120V circuits. Designed to support essential appliances like refrigerators, TVs, and PCs, these units help maintain stable power delivery without overpromising results. The goal is to reduce the impact of voltage irregularities on everyday equipment, so you can enjoy smoother operation and fewer surprises when the power fluctuates.

Each protector offers comprehensive voltage protection that automatically cuts power if the supply goes beyond safe levels. Specifically, if voltage rises above 140 VAC or falls below 90 VAC, the unit disengages to help shield connected devices from abrupt spikes or drops. This behavior is intended to minimize stress on compressors, motors, and electronics during normal household voltage events, storms, or city grid fluctuations.

See status at a glance

Four LED indicators provide a clear, at-a-glance readout of the system status. Normal voltage, High voltage, Low voltage, and Delay status are all easy to distinguish, making monitoring straightforward for busy households. The plug-and-play design means setup is simple and requires no specialized tools or configuration.

• Normal Voltage indicates safe operating range for connected devices.
• High Voltage signals elevated supply levels requiring attention.
• Low Voltage shows reduced supply that could affect performance.
• Delay indicates protective mode is active until conditions stabilize.

Key protections and safe handling

• Overvoltage protection triggers at 140 VAC to shield components from spikes.
• Undervoltage protection triggers below 90 VAC to help prevent weak motor starts.
• Delay protection suspends output during instability, allowing a safe restart once the voltage stabilizes.
• Stable operation includes a built-in 3 minute stabilization interval before power returns to the outlet.

Versatile compatibility for home essentials

Engineered for high power appliances, this protector is suitable for refrigerators, freezers, air conditioners, ice machines, washing machines, and other large electrical loads. Use it where consistent power delivery matters and room for placement near the appliance is available.

Easy setup and practical placement

The unit supports quick plug-and-play installation and a compact footprint that fits neatly on countertops, shelves, or behind appliances. The 2-pack option provides flexibility to shield multiple devices around the home or office, giving you a consistent approach to basic power protection without clutter.
