Single Outlet Surge Protector

The Cable Matters 402042 converts a standard wall receptacle into a single surge-protected grounded outlet. Rated for 15 amps and 1875 watts at 125 volts, it handles televisions, computers and small appliances. A built-in LED shows whether the 490-joule protection circuit is still active. The white housing fits flush without blocking the adjacent socket.

Indoor Electronics Protection

This plug suits owners who want surge suppression for individual devices such as a TV, desktop or kitchen appliance without a bulky strip. It is not for buyers who need more than one protected outlet per location. It is not for installations that require a 500-volt or 750-joule clamping rating. It is not for outdoor, damp or hard-wired applications.

490 Joule Energy Rating

The protector absorbs up to 490 joules of surge energy with an 800-volt L-N rating. ETL listing confirms compliance with applicable safety standards. The 15-amp, 1875-watt capacity matches standard household circuits. If your equipment demands a higher joule rating or a lower clamping voltage, this model will not meet that requirement.

Questions about this item

What clamping voltage does the 490 joule surge protector limit surges to?

The surge protector clamps transient voltage at 500V line-to-neutral, limiting the spike that reaches connected equipment.

Does the non-blocking single outlet leave the adjacent wall receptacle free?

Yes, the compact housing fits within one outlet space so the second receptacle on the duplex remains usable.

How is the surge protector installed and what common step is missed?

Plug the unit directly into a grounded 3-prong wall outlet; the step often missed is verifying the green LED lights to confirm active protection.
