7 Best Surge Protectors For Refrigerator 2023 [Buying Guide]

Refrigerators are a vital component of a modern household. Not only do they keep our food fresh and healthy, but they also help us save money and time by reducing the need for frequent grocery shopping.

However, these appliances can be vulnerable to power surges that can damage their internal components and lead to costly repairs.

Hence, investing in a high-quality surge protector for your refrigerator is a wise decision that can save you from the inconvenience of unexpected breakdowns.

But with an overwhelming number of options available in the market, it can be challenging to choose the best surge protector for your refrigerator.

That’s where I come in. In this blog post, I’ve compiled a list of 7 surge protectors for refrigerators that offer reliable protection against power surges, voltage spikes, and electrical noise.

Why Should You Trust This List?

I have done some extensive research, and I am confident I have found the best surge protector for most people.

For accuracy, I asked people who use these protectors for their refrigerators what they thought, and I’ve been using one myself for a while.

Out of all the options, Tripp Lite’s IBAR2-6D surge protector stands out. It has a 12-amp circuit breaker and two outlets, and it provides 1440 joules of surge protection. In my experience, it’s one of the best refrigerator surge protectors on the market.

Safeguarding Your Fridge: What to Look for in a Quality Surge Protector

Safety Rating

The UL 1449 standards cover how electrical surge protective devices (SPDs) like receptacles and plug-in type ESPDs for electrical circuits are made, how they work, and how they are tested.

So try to purchase a model that has a UL certification for durability and safety. This standard will ensure you protect your appliances from voltage surges.

Voltage Clamping

Voltage clamping is when the voltage is held at a specific level. This is done for a number of reasons, including to prevent damage to equipment that is plugged into the surge protector.

If the voltage of your refrigerator is less than the voltage of your surge protector, you will have electrical problems inside.

Also, make sure the clamping voltage is lower than the minimum operating voltage of your system to prevent electrical problems.

Joule Rating

The joule rating is the amount of energy that your refrigerator’s surge protector should take. A higher rating will ensure the best protection for a laptop, refrigerator, computer, or home.

So for your fridge surge protector, try to look for a rating over 1000 joules. If you have a high budget, you should buy a surge protector with the highest joule rating.

Diagnostic LEDs

Diagnostic lights and indicators confirm power protection and line error status. So you should ensure your refrigerator surge protector has diagnostic LED lights that can verify power and protective status.

It also indicates line problems, making it easy for you to know if there is a power problem or not. So I recommend you buy one that has at least one indicator light.


Extended warranties indicate the excellent qualities of the surge protector. However, all surge protector manufacturers are not the same, and the quality of the protectors they produce varies.

Also, some do not provide warranties for their products. I don’t think a warranty product is terrible, but if the product has a warranty, that’s fine.
