Refrigmatic WS-36300 Electronic Voltage & Surge Protector for Refrigerators Up to 27 cu. ft. (2 Pack)
Quick take
The Refrigmatic WS-36300 is an electronic refrigerator surge protector that watches for both high and low voltage, then shuts power off outside its safe range. It is designed for refrigerators up to 27 cu. ft., ice makers, and air conditioners up to 5000 BTU, with LED indicators to show normal, waiting, high, or low voltage states. The key caveat is that during unstable power, it will interrupt your appliance briefly (with a delay) to protect it, so you need to be okay with that behavior.
Pros and cons
Pros
- Monitors voltage continuously and cuts power when it goes outside the set high and low thresholds (140 VAC high, 90 VAC low).
- Protection timing behavior is part of the design, including a 3-minute waiting period at first use and a delay after a high-voltage event.
- Clear status indicators for normal voltage, waiting cycle, high voltage, and low voltage.
- Space-saving angled outlet helps when you need to place a refrigerator closer to the wall.
- 2-pack option for covering a second fridge/freezer or stocking a spare.
Cons
- Power interruptions are possible during voltage problems, which can be inconvenient even though it is meant to protect the appliance.
- Narrower device focus (refrigerators up to 27 cu. ft., ice makers, and A/C up to 5000 BTU). Other electronics may need a different protector.
- No second outlet for chaining multiple appliances from one unit (it is listed for 1 outlet).
What buyers think
Buyer-review evidence is strongly supportive of the protector’s “cut off then reconnect after a delay” behavior when power conditions become unstable. Reviewers commonly describe it shutting off during surges or outages and restoring power after a waiting period, with comments tying the device to fewer issues like blown refrigerator parts in homes experiencing power interruptions or voltage-related problems. Some buyers also mention that it does not prevent every breaker trip in more complex scenarios, but they still report that the unit responds by disconnecting and then rebooting after the delay.
Overall, the recurring theme is that the WS-36300 behaves predictably under poor power, and that the delay is expected rather than a malfunction. Since the review evidence provided is limited to a handful of snippets, sentiment beyond that theme (for example, long-term durability) is not strong enough to generalize with confidence.
How the WS-36300 protects your refrigerator
This is not just a basic surge-only strip. It is an electronic voltage protector intended for large appliances that are sensitive to voltage swings, including refrigerators (up to 27 cu. ft.), ice makers, and air conditioners up to 5000 BTU. The unit is designed to continuously monitor the line voltage and disconnect the load if voltage runs outside the allowed range.
- High-voltage cutoff: power is shut off when voltage rises above 140 VAC.
- Low-voltage cutoff: power is shut off when voltage drops below 90 VAC.
- Delay and reconnection: the unit uses a delay cycle before restoring power after a high-voltage event (the product notes a 3-minute delay, including a waiting period after first use).
- Status lights: LED indicators help you identify whether the unit is in normal voltage, waiting cycle, high-voltage, or low-voltage mode.
Key specs that matter for shopping
- Designed outlet setup: listed as 1 outlet (with an angled outlet design for easier placement).
- Voltage rating reference: the listing references 135 volts among its electrical details.
- Surge energy capacity: 303 joules.
- Maximum current: 10.85 amps.
- Plug type: Type B (North American, 3-pin).
- Form factor: compact body sized about 10 in x 7 in.
Pros and cons by buyer fit
Best for
- Homes that see frequent voltage swings, including brownouts or brief surges that can stress refrigerator electronics.
- Refrigerators and freezers in the 27 cu. ft. class (plus compatible ice makers and small A/C units).
- People who want visibility into what the protector is doing via normal/high/low and waiting indicators.
- Buyers who want two units to cover two appliances or keep a spare.
Who should consider other options
- If you need multiple outlets from one protector, you may prefer a model designed for more plug capacity.
- If your appliance falls outside the stated capacity guidance (refrigerators larger than 27 cu. ft., or A/C beyond 5000 BTU), this one may not be the right category fit.
- If you cannot tolerate any power interruption, note that a voltage protector must disconnect under out-of-range conditions to do its job.
Is it worth it?
The Refrigmatic WS-36300 is worth considering if your goal is appliance protection specifically for refrigerators, ice makers, and small A/C units, and you want a protector that actively responds to both high and low voltage rather than only clamping spikes. The strongest reason to buy is the combination of voltage cutoffs, a built-in delay behavior, and clear LED status. The main reason to pause is that you should expect occasional disconnects during unstable power, because that is part of the protective function.
If you are shopping on a budget, comparing joule rating and whether the device includes low-voltage shutoff plus a reconnection delay can help you choose a model that matches how your home’s power behaves.

FAQ
What size refrigerators is the WS-36300 meant for?
It is recommended for domestic refrigerators up to 27 cu. ft., along with ice makers and air conditioners up to 5000 BTU.
What does it do when voltage is too high or too low?
It is designed to shut off the connected load when voltage goes outside its safe range, with a stated cutoff at 140 VAC (high) and 90 VAC (low).
How long is the delay before power returns?
The product notes a 3-minute waiting time, including after first use, and it also uses a delay cycle before reconnecting after a high-voltage event.
Will it protect during power outages?
It is designed to handle brownouts and voltage swings by disconnecting the load when conditions are out of range and then restoring power after the delay once voltage stabilizes.
Does it have more than one outlet?
The listing indicates 1 outlet for the unit.
Refrigmatic WS-36300 faqs
- Can I use the WS-36300 for appliances other than a refrigerator?It is specifically guided for domestic refrigerators (up to 27 cu. ft.), ice makers, and air conditioners up to 5000 BTU. For other electronics, you will want to compare compatibility and electrical ratings.
- What do the indicator lights mean?The unit includes light indicators for normal voltage, waiting cycle, high voltage, and low voltage so you can quickly see what state it is in.
- Why does the protector sometimes “turn off” even when I just want the fridge to keep running?When voltage is outside its stated safe range, the protector disconnects power to reduce the risk of damage, and it then waits before reconnecting.
