Refrigmatic Refrigerator Voltage & Surge Protector WS-36300 — 2-Pack, 303-Joule Auto Cutoff & 3-Minute Restart

Refrigmatic WS-36300 is an electronic voltage and surge protector designed to shield refrigerators (up to 27 cu. ft.), ice makers, and small air conditioners from high/low voltage, brownouts, spikes and surges.

Power fluctuations can damage compressors, electronics, and seals in refrigeration equipment. The WS-36300 combines automatic voltage cutoff, a 303-joule surge capacity, and a timed restart delay so appliances are only re-energized when mains voltage returns to a safe range. Packaged as a two-unit set, each protector fits behind large appliances and features status lights that make it easy to see whether your fridge is receiving safe power or is in a protective wait state.

How does the WS-36300 guard my refrigerator against voltage problems?

This unit watches incoming voltage and cuts power when levels stray outside safe thresholds. It stops surges and brownouts from reaching sensitive appliance components, and restarts automatically after a short safety delay once conditions normalize.

• Shuts off at 140 VAC for high voltage and at 90 VAC for low voltage
• 303-joule surge capacity to absorb transient spikes
• Automatic 3-minute delay before reconnecting after an event
• LED indicators show normal, high, low, and delay status

Will this protector work with my refrigerator or freezer?

The WS-36300 is sized for domestic refrigerators up to 27 cubic feet and similarly powered appliances. It’s also appropriate for ice makers and window-style air conditioners up to about 5,000 BTU, giving reliable protection across common household units.

• Rated for refrigerators up to 27 cu. ft.
• Compatible with ice makers and small ACs (≤5000 BTU)
• Designed for typical household split-phase voltage ranges
• Compact footprint fits behind most appliances without blocking airflow

What safety and convenience features does it offer during and after an outage?

When voltage becomes unsafe the protector cuts power to prevent damage. After the grid stabilizes, the WS-36300 waits three minutes to allow capacitors and compressors to settle, then restores power only if voltage is within safe limits, helping prevent short cycling and further stress.

• Visible "Delay Time" LED during the 3-minute restart period
• Prevents immediate re-energizing after a surge to protect compressors
• Simple plug-and-play installation with an angled outlet for space savings
• Two-pack lets you protect primary and secondary units or keep a spare

How does the physical design help with installation and placement?

The WS-36300 is narrow and intended to sit behind refrigerators without taking up much room. An angled outlet lets appliances be pushed closer to walls, and the unit’s LED indicators are positioned so you can check status without moving the fridge.

• Angled outlet reduces gap between appliance and wall
• Compact housing designed for tight spaces behind large appliances
• Visible lights for quick power-status checks from the side or back
• Two-pack format offers flexible placement or backup protection

Who is this for: The Refrigmatic WS-36300 is a practical choice for homeowners, renters, and small-business operators who rely on refrigerators, freezers, or compact air conditioners and want simple, automated protection from voltage irregularities. It’s especially useful in areas with frequent brownouts, unstable grid supply, or where appliance replacement would be costly—offering a straightforward, space-conscious solution to prolong appliance life and reduce repair risk.
