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 utilizes six grounded outlets arranged in three molded outlet pairs together with an illuminated rocker power switch. The enclosure incorporates a textured finish that differs from the smoother plastics commonly used on many later surge protectors.

Although limited documentation of the model has presently been identified, surviving examples suggest that the CO-001S was marketed during the period when Taiwanese manufacturers supplied large numbers of surge protectors and power-distribution products for North American consumers.

The documented example was acquired as part of the OldSurge Archive's efforts to document lesser-known manufacturers whose products are increasingly absent from modern electrical-equipment markets.

Historical Context

COXOC was historically associated with surge protectors, power strips, and related electrical accessories. However, as documented by the archive's October 2026 review of the company's website, contemporary product offerings emphasize electronic connectors and related technologies rather than surge-protection products.

The CO-001S appears representative of the surge-protector designs commonly sold during the 1990s, a period when many consumer surge suppressors emphasized outlet count, illuminated power switches, and basic surge protection while retaining relatively simple external designs.

The model may provide insight into a product category that is no longer prominently represented within COXOC's modern product lineup.

Physical Characteristics

The enclosure incorporates a heavily textured exterior finish across both enclosure halves. Unlike many later surge protectors that utilize smooth exterior surfaces, the CO-001S employs a pebble-textured finish throughout the housing.

The enclosure measures approximately 10.25 inches (26.0 cm) long and 1.56 inches (4.0 cm) wide. The outlet section is approximately 1.13 inches (2.9 cm) tall, while the raised switch housing increases overall height to approximately 1.50 inches (3.8 cm).

The housing features a distinctive raised section at the cord-entry end that accommodates the illuminated rocker power switch. The switch housing transitions downward to a lower outlet section that extends the remainder of the enclosure length.

The six receptacles are arranged in three visually distinct outlet pairs separated by molded divider lines. This grouping creates a symmetrical appearance and distinguishes the CO-001S from many contemporary surge protectors that utilize uninterrupted outlet rows.

The outlet end of the enclosure incorporates a rounded profile with no visible external controls, indicators, or mounting hardware.

The cord-entry end incorporates a resettable circuit breaker positioned adjacent to the molded strain-relief assembly. The breaker utilizes a black push-button reset mechanism accessible from the exterior of the enclosure.

The underside of the enclosure incorporates a molded regulatory-information panel containing electrical ratings, model identification, surge-suppression information, UL listing information, and country-of-origin markings.

Unlike many later surge protectors that utilize printed or adhesive labels, the CO-001S incorporates this information directly into the enclosure tooling through molded lettering.

Two keyhole-style wall-mounting slots are provided to allow the unit to be mounted to vertical surfaces. The bottom panel is secured using multiple recessed fasteners.

A resettable circuit breaker is accessible from the cord-entry end of the enclosure through a black push-button mechanism adjacent to the molded strain-relief assembly.

The underside incorporates two keyhole-style mounting slots that permit wall or furniture mounting. The mounting slots are located near opposite ends of the enclosure and are molded directly into the bottom housing.

Regulatory and electrical information is molded directly into the enclosure rather than applied as a printed or adhesive label. This approach permanently preserves model and rating information and was commonly encountered on certain consumer surge suppressors of the era.

The documented example utilizes a molded straight-blade NEMA 5-15P attachment plug connected to a three-conductor SJT power cord. Visible cord markings identify the assembly as utilizing 14 AWG conductors and UL file number E55351.

The molded plug body follows a conventional straight-blade design and lacks external manufacturer branding.

Date Codes

The documented example is identified as model CO-001S.

The molded regulatory-information panel confirms a maximum electrical rating of 125 volts, 15 amperes, and 60 hertz together with a transient suppression voltage rating of 330 volts.

The unit incorporates UL file number E147475 and is marked as manufactured in China.

Additional molded markings are present on interior enclosure surfaces. A single molded numeral, appearing to be either "5" or "2", is present within the upper enclosure. The significance of this marking has not been determined but may represent a tooling, cavity, or mold-identification mark rather than a manufacturing date.

No serial number or manufacturing-date information has presently been identified on the exterior of the documented example.

Condition Upon Acquisition

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

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

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

Examination of the attachment plug revealed localized discoloration adjacent to the current-carrying blades together with minor separation 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. The specific cause cannot be determined from visual examination alone, although prolonged operation of high-current loads, poor receptacle contact tension, or similar conditions may have contributed to the observed damage.

A second archived COXOC CO-001S example does not presently exhibit comparable discoloration or plastic separation, suggesting the condition may be specific to the documented example rather than an inherent design characteristic.

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

The attachment plug is particularly significant because it incorporates the only manufacturer branding presently identified on the documented example. The molded COXOC logo provided the evidence necessary to associate the model with COXOC and distinguish it from numerous otherwise similar generic surge-protector designs.

The unit was cleaned prior to detailed photography, testing, and further examination.

Functional Testing

The documented example was tested for basic electrical operation, switch functionality, and outlet wiring integrity.

When connected to utility power, the rocker switch successfully controlled power to the protected outlets. Functional testing confirmed that the unit remained operational.

No illumination was observed from the rocker switch during testing. It has not yet been determined whether the switch incorporates a failed indicator lamp or was originally manufactured without switch illumination despite its appearance.

Testing with a receptacle tester confirmed correct hot, neutral, and ground connections at the protected outlets. No open grounds, open neutrals, reversed polarity conditions, or other wiring faults were detected.

The documented example passed all functional testing performed during documentation and remained operational at the time of examination.

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 primarily of a stamped-metal outlet-contact assembly, a resettable circuit breaker, and a single metal-oxide varistor (MOV) connected between the hot and neutral conductors.

Unlike many surge protectors documented by the archive, the CO-001S does not utilize a dedicated printed-circuit board. Instead, the MOV is connected directly into the wiring assembly near the circuit breaker.

Power enters through the attached cord before passing through the resettable circuit breaker and power switch assembly. Electrical distribution is provided by a long stamped-metal contact structure extending the length of the outlet section.

The surge-suppression circuit consists of a single MOV connected between the hot and neutral conductors. No additional MOVs, filtering inductors, capacitors, or supplementary suppression components were observed.

The design represents one of the simplest surge-suppression implementations currently documented by the OldSurge Archive and appears focused on basic transient suppression while minimizing component count and manufacturing complexity.

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

The upper enclosure incorporates molded outlet guides, structural reinforcement ribs, mounting features, and screw bosses that help maintain alignment of the outlet-contact assembly and enclosure components.

Electrical distribution is provided by a long stamped-metal contact assembly extending the length of the receptacle section. This assembly provides both electrical continuity and mechanical support for the outlet contacts.

The internal construction is notably minimalist. Unlike many surge protectors documented by the archive, the CO-001S does not utilize a dedicated printed-circuit board. Surge suppression is provided solely by a single metal-oxide varistor (MOV) connected between the hot and neutral conductors.

No additional MOVs, line-to-ground suppression paths, inductive filtering components, capacitors, indicator circuitry, or thermal protection devices were observed.

The design represents one of the simplest surge-suppression implementations currently documented by the OldSurge Archive and appears optimized for low component count and straightforward manufacture.

Comparison Notes

Compared with many surge protectors documented by the archive, the COXOC CO-001S utilizes an unusually simple surge-suppression design. Whereas products from APC, Universal, Globe Electric, and other manufacturers frequently incorporate multiple MOVs, dedicated suppression boards, filtering components, and indicator circuitry, the CO-001S relies upon a single MOV connected directly across the incoming power conductors.
