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.

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.

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.
Additional condition information pending documentation.
Teardown
