What to Look For in a Refrigerator Surge Protector

There are a couple of things to keep an eye on when looking for the best surge protector for your refrigerator. We’ve summarized these key features below:

Number of Sockets

Optimizing the number of sockets is crucial when selecting a surge protector. For those with dual refrigerators, a two-socket protector is essential. While a single socket can be expanded using an extension lead, this often results in extra costs and unnecessary clutter. Plan your socket needs in advance to ensure your surge protector aligns perfectly with your appliances.

Joule Rating

The joule rating refers to how much energy your refrigerator surge protector can absorb. A higher joule rating equals better protection.

So how many joules of surge protection do you need? The answer depends on what you’re protecting – are you protecting a PC, refrigerator, or even a whole home?

Here are some rough joule rating guidelines:

A unit with up to 1000 joules of surge protection is enough for small electronics.
A surge protector with 1000 to 2000 joules will provide sufficient protection for refrigerators, washing machines & dryers, office equipment, and power tools.
Consider the highest joule rating (2000+) for expensive gaming consoles, home theater systems, and any computer that stores important data. Anything that is very expensive or irreplaceable.

So for your refrigerator surge protector, look for a joule rating between 1000 to 2000.

Safety Rating

Navigating through various safety standards can be daunting, yet it’s vital for your surge protector. The key standard to seek is UL (Underwriters Laboratories), a benchmark in safety certification. This ensures your device meets rigorous safety criteria, providing peace of mind and reliable protection.

UL is one of several companies approved to perform safety testing by the U.S. federal agency Occupational Safety and Health Administration (OSHA). OSHA has a list of approved testing laboratories, which are recognized as Nationally Recognized Testing Laboratories.

Even within UL though, there are a bunch of safety standards that could apply. For proper refrigerator surge protection, you’re mainly want to be looking at the UL 1449 safety standard.

UL 1449 is the Underwriters Laboratories Safety Standard for Surge Protective Devices (SPD) – i.e. perfect for refrigerator surge protection.

So make sure your refrigerator surge protector confirms to UL 1449.

Clamping Voltage

Understanding clamping voltage is crucial—it’s the threshold where your surge protector starts to block excess voltage, safeguarding your refrigerator. Ensuring this value is appropriate means your appliance gets optimal protection without the risk of voltage overload.

For example, a refrigerator surge protector might limit a 6,000V surge so that only 600V is ‘visible’ to the load. Hence here the clamping voltage for this refrigerator surge protector is 600V.

If the clamping voltage is too high, then the surge protector will allow too much voltage to pass to your refrigerator (which will break it).

CHECK the maximum rated voltage of your refrigerator before buying a surge protector, so make sure that the clamping voltage of your refrigerator surge protection device is LOWER than the maximum operating voltage of your refrigerator.

In general, though, the clamping voltage should be LESS than 700V for a refrigerator surge protector.

Warranty

A substantial warranty signifies more than just extended coverage—it reflects the manufacturer’s confidence in their surge protector’s durability and reliability. Opt for a product that offers a lengthy warranty, as it ensures long-term security and value.

Not just for the obvious reason that if something goes wrong, you’ll be able to make a claim, but for the signal that a long warranty implies about the quality of the refrigerator surge protector (or rather, the confidence the supplier has for the refrigerator surge protector).

If suppliers gave out generously long warranties for refrigerator surge protectors that went bust after 2 weeks, they wouldn’t be around for very long.

So you want to long for longer warranties and high insurance payouts on your refrigerator surge protector (from companies that have been around for more than five years).

EMI/RFI Noise Filtering

EMI and RFI stand for Electromagnetic Interference and Radio Frequency Interference, respectively. While distinct, both can affect your appliances. A quality surge protector filters out these interferences, ensuring your refrigerator operates smoothly without disruptive noise.

Many filters – e.g. low pass filters, high pass filters, or band pass filters – only allow certain types of frequencies through, meaning a set range of EMI/RFI emissions will be transmitted to the device being protected.

This is because certain EMI/RFI emissions will not interfere with the performance frequencies of different electric and electronic devices.

So the goal of EMI/RFI is noise filtering is to remove electromagnetic and radio frequency interference that will interfere with the refrigerator surge protection.

So look for refrigerator surge protectors that have EMI/RFI emissions.
