Radio Shack 61-2140 Appliance Surge Protector
Radio Shack 61-2140 Appliance Surge Protector
Overview
The Radio Shack 61-2140 Appliance Surge Protector is a single-outlet surge protector marketed for appliance and consumer-electronics applications.
The documented example was manufactured in Mexico and represents the first Radio Shack–branded surge protector documented by the OldSurge Archive.
Unlike most surge protectors documented by the archive, the documented example was found to be non-functional during testing and did not pass utility power to a connected load.

Weight
The documented example weighs approximately 12.4 oz (352 g).
The relatively low weight is consistent with the device's compact dimensions, four-foot power cord, and comparatively simple construction.
Physical Description
The Radio Shack 61-2140 utilizes a relatively simple enclosure consisting of a six-outlet receptacle section and a combined rocker-switch and control section.
All six outlets are arranged in a standard receptacle orientation and are spaced evenly along the length of the device.
Unlike several higher-end surge protectors documented elsewhere in the archive, the 61-2140 does not incorporate transformer-spaced outlets, rotated receptacle orientations, telephone-line protection, coaxial protection, or diagnostic indicators.
Unlike some surge protectors intended for computer equipment, the six outlets are closely spaced and do not accommodate large transformer-style power adapters without blocking adjacent receptacles.
The Radio Shack 61-2140 utilizes a narrow rectangular enclosure with a widened control section incorporating a rocker switch.
The six outlets are arranged in a standard receptacle orientation and are positioned with relatively little spacing between adjacent outlets. The design does not provide dedicated transformer-spaced outlets for large plug-in power adapters.
The enclosure is notably compact and low in profile, measuring approximately 10.38 inches (26.4 cm) in length while standing only about 1 inch (2.5 cm) tall.
The underside incorporates four keyhole-style mounting slots that support wall or surface mounting.
The design utilizes a separate resettable circuit breaker located at the cord-entry end of the device.
At 12.4 oz (352 g), the Radio Shack 61-2140 is among the lighter surge protectors documented by the OldSurge Archive.

Testing
The documented example was tested for basic electrical operation.
During testing, no output voltage was present at the protected receptacle, and utility power was not passed to a connected load.
No additional troubleshooting was performed to determine the specific cause of the failure.
The documented example is therefore considered non-functional as documented.
Condition Upon Acquisition
The documented example was acquired for preservation and documentation by the OldSurge Archive.
The enclosure exhibited light dust accumulation, minor cosmetic wear, and moderate discoloration of the attached power cord consistent with age and prior use.
No significant cracking, melting, or external physical damage was observed.
The unit was cleaned prior to detailed documentation and photography.
Teardown
Teardown documentation pending.
