COXOC CO-001S Variant (OS-0030)

The COXOC CO-001S (Variant OS-0030) is a documented example of the COXOC CO-001S six-outlet surge protector preserved by the OldSurge Archive.

Although externally similar to the previously documented CO-001S specimen, this example exhibits several notable differences including a shorter power cord, lower overall weight, an illuminated rocker switch that remains functional, and a power-cord assembly bearing COXOC branding rather than the Apollo-manufactured cord identified on the archive's first documented example.

The specimen provides evidence that multiple manufacturing variations of the CO-001S were produced and demonstrates how apparently identical consumer surge protectors often incorporated different components, suppliers, and construction details during production.

Overview

The COXOC CO-001S is a consumer surge protector intended to provide both surge suppression and AC power distribution for computers, peripherals, office equipment, and household electronics.

The design incorporates six grounded outlets arranged in three molded pairs, a rocker power switch, a resettable circuit breaker, and a permanently attached power cord. Its heavily textured enclosure and stepped switch housing give the unit a distinctive appearance compared with many later surge protectors utilizing smoother case designs.

Limited documentation of the model has presently been identified. Surviving examples suggest that the CO-001S originated during a period when Taiwanese manufacturers supplied large quantities of surge protectors and power-distribution products to North American consumers, often under lesser-known brand names.

The documented example was acquired as part of the OldSurge Archive's efforts to preserve and document products from manufacturers that have largely disappeared from the consumer surge-protection market.

Significance

The documented specimen is significant because it demonstrates variation within the COXOC CO-001S product line.

At first glance the unit appears nearly identical to the archive's previously documented example. Closer examination, however, revealed differences in cord length, overall weight, switch functionality, and power-cord markings.

These variations suggest that COXOC may have sourced components from multiple suppliers or introduced manufacturing revisions during the production life of the model. Such differences are common among consumer electrical products of the 1990s but are often undocumented.

The specimen therefore provides a useful reference for understanding manufacturing variation within low-cost consumer surge protectors.

Weight

The documented example weighs approximately 14.3 ounces (405 g).

Despite incorporating six grounded outlets, a 15-amp resettable circuit breaker, a full-length stamped-metal outlet-contact assembly, and a 14 AWG power cord, the CO-001S is among the lighter surge protectors currently documented by the archive.

The relatively low weight reflects the unit's compact dimensions and highly simplified surge-suppression design. Compared with many contemporary surge protectors preserved by the archive, the CO-001S utilizes fewer internal components while maintaining a full 15-amp electrical rating.

Physical Characteristics

The COXOC CO-001S utilizes a compact rectangular enclosure measuring approximately 10.25 inches (26.0 cm) long and 1.56 inches (4.0 cm) wide. The receptacle section is approximately 1.13 inches (2.9 cm) tall, while a raised housing at the cord-entry end increases overall height to approximately 1.50 inches (3.8 cm).

A heavily textured pebble-grain finish is molded into both enclosure halves. This textured appearance distinguishes the CO-001S from many later surge protectors that utilize smoother exterior surfaces.

The upper surface incorporates six grounded receptacles arranged in three outlet pairs separated by molded divider lines. The paired arrangement creates a distinctive appearance and visually differs from the uninterrupted outlet rows commonly found on many competing designs.

The raised cord-entry housing contains a red rocker power switch together with an externally accessible resettable circuit breaker. The outlet end of the enclosure incorporates a simple rounded profile and does not contain additional indicators or controls.

The underside incorporates two keyhole-style mounting slots intended for wall or furniture mounting. Regulatory and electrical information is molded directly into the bottom enclosure rather than applied using a printed or adhesive label. The molded panel identifies the model number, electrical ratings, surge-suppression voltage rating, UL file number, and country of manufacture.

The documented example utilizes a molded straight-blade NEMA 5-15P attachment plug connected to an Apollo-manufactured SJT 14/3 power cord. Cord markings identify three 14 AWG conductors together with UL file number E55351 and CSA file number LL34977.

Although the surge protector itself carries no prominent external manufacturer branding, the attachment plug incorporates a molded COXOC logo that provided the evidence necessary to positively identify the manufacturer.

Date Codes

No serial number, manufacturing date, or date-code markings have presently been identified on the exterior of the documented example.

The molded regulatory-information panel identifies the unit as model CO-001S, confirms a maximum electrical rating of 125 volts, 15 amperes, and 60 hertz, and specifies a transient suppression voltage rating of 330 volts. The panel also identifies UL file number E147475 and confirms manufacture in China.

Additional molded markings are present within the enclosure. A single numeral resembling either "5" or "2" is molded into the interior of the upper housing. Although its significance has not been determined, the marking appears more likely to represent a tooling, cavity, or mold identifier than a manufacturing-date code.

In the absence of documented date codes, packaging, manufacturer literature, or other independent manufacturing evidence, the production date of the documented example presently remains undetermined. Based upon overall design characteristics and construction methods, however, the unit likely dates to the consumer-computing era of the 1990s.

Condition Upon Acquisition

The documented example was acquired in used condition and exhibited light cosmetic wear consistent with long-term residential or office use.

The textured enclosure remained structurally intact and displayed only minor scuffs, scratches, and accumulated dust. Compared with many similarly aged surge protectors preserved by the archive, discoloration was relatively modest and the housing retained a generally uniform appearance.

The attached power cord, strain-relief assembly, rocker switch, and receptacles appeared complete and undamaged upon initial examination.

The most significant condition-related observation involved the attachment plug. Localized discoloration was present adjacent to both current-carrying blades, and minor separation was visible between the blade assemblies and the surrounding molded plastic body.

The condition is consistent with previous exposure to elevated temperatures at the attachment-plug interface. Although the exact cause cannot be determined from visual examination alone, prolonged operation under high electrical load, poor receptacle contact tension, or similar service conditions may have contributed to the observed damage.

Notably, a second archived COXOC CO-001S example does not exhibit comparable discoloration or blade separation, suggesting that the condition is specific to the documented example rather than an inherent characteristic of the product design.

The attachment plug proved particularly important during documentation because it incorporates the only visible COXOC branding presently identified on the artifact. The molded logo provided the evidence necessary to positively associate the model with COXOC and distinguish it from numerous otherwise similar generic surge protectors.

The documented example was photographed in its final service location prior to retirement and documentation. No equipment was connected to the unit at the time the photograph was taken.

The unit was subsequently cleaned prior to detailed photography, testing, and teardown.

Functional Testing

The documented specimen successfully passed basic operational testing.

When connected to utility power, the rocker switch controlled power delivery to all receptacles and the integrated switch lamp illuminated normally when the unit was switched on.

Testing with a receptacle tester confirmed proper hot, neutral, and ground connections at the protected outlets.

Unlike the archive's first documented CO-001S example, this specimen retained a functioning illuminated switch. The observation indicates that at least some CO-001S units originally incorporated lamp-equipped rocker switches rather than non-illuminated switch assemblies.

Teardown

The COXOC CO-001S enclosure is secured using three Phillips-head screws and can be opened non-destructively.

Removal of the upper housing revealed an unusually simple internal construction consisting of a stamped-metal outlet-contact assembly, a resettable circuit breaker, a rocker power switch, and a single metal-oxide varistor (MOV) providing surge suppression.

Power enters through the attached Apollo-manufactured SJT 14/3 power cord before passing through a RONG FENG RF-112B resettable circuit breaker rated 15 amperes at 125 volts AC. Electrical distribution is accomplished through a long stamped-metal contact assembly extending the length of the enclosure and serving all six receptacles.

Unlike many surge protectors documented by the archive, the CO-001S does not utilize a printed-circuit board. Surge suppression is provided solely by a single SAS 241KD14 metal-oxide varistor connected directly between the hot and neutral conductors using short wire leads and soldered connections.

No additional MOVs, line-to-ground suppression paths, filtering inductors, capacitors, thermal cutoffs, indicator circuitry, or other supplemental surge-suppression components were observed. The design therefore represents one of the simplest surge-suppression implementations currently documented by the OldSurge Archive.

Despite the simplicity of the suppression circuitry, the unit incorporates a substantial stamped-metal outlet-contact assembly, a full 15-amp resettable circuit breaker, and a 14 AWG power cord. The design appears to prioritize robust power distribution while providing only basic transient-voltage suppression.

The documented MOV remains commercially available through modern electronic-component distributors. Contemporary component documentation identifies comparable 241KD14 devices as 14 mm MOV surge suppressors intended for AC power-line protection applications.

UL certification records additionally confirm that the RONG FENG RF-112B belongs to a certified supplementary-protector product family manufactured by Rong Feng Industrial Co., Ltd.

No evidence of overheating, damaged conductors, arcing, failed components, or internal electrical failure was observed. Internal components appeared consistent with normal long-term use.

The observed heat-related damage at the attachment plug therefore appears unrelated to any obvious internal failure within the surge protector itself.

Comparison Notes

The COXOC CO-001S occupies a distinctive position within the OldSurge Archive because it demonstrates an unusually minimalist approach to surge protection. Unlike products from APC, Universal, Globe Electric, PowerSentry, and other manufacturers that incorporate multiple surge-suppression components, dedicated circuit boards, filtering networks, or diagnostic indicators, the CO-001S relies upon a single metal-oxide varistor connected directly across the incoming AC supply.

Despite the simplicity of its suppression circuitry, the unit incorporates several comparatively robust power-distribution features including a full 15-amp resettable circuit breaker, an Apollo-manufactured 14 AWG SJT power cord, and a substantial stamped-metal outlet-contact assembly extending the length of the enclosure.

The resulting design appears to emphasize reliable power distribution, straightforward manufacturing, and low component count while providing basic transient-voltage suppression. As such, the CO-001S provides a useful reference point for understanding the lower-complexity end of the consumer surge-protector market.

Recall Information

No recall information has presently been identified for the COXOC CO-001S.

Historical References

Teardown examination identified several components for which modern documentation remains available.

Surge suppression within the documented example is provided by a SAS 241KD14 metal-oxide varistor (MOV). Comparable 241KD14 devices remain commercially available through modern electronic-component distributors and continue to be marketed for AC power-line surge-suppression applications.

The CO-001S also incorporates a RONG FENG RF-112B resettable circuit breaker. Contemporary UL certification records identify the RF-112B as part of a certified supplementary-protector product family manufactured by Rong Feng Industrial Co., Ltd.
