Despite these differences, teardown examination demonstrated that the internal surge-protection circuitry, outlet-contact assemblies, circuit breaker, enclosure design, and overall construction remained substantially identical.

			Internal examination revealed no significant design differences between OS-0028 and OS-0030. Both specimens utilize the same enclosure design, stamped-metal outlet-contact assembly, RONG FENG RF-112B circuit breaker, SAS 241KD14 metal-oxide varistor, and three-screw construction method.

			The primary documented differences are therefore limited to the power-cord assembly, cord length, overall weight, plug condition, and switch-lamp operation.

			The evidence suggests that COXOC maintained a consistent internal electrical design while sourcing different cord assemblies during production of the CO-001S.

The housing remained structurally intact and retained the textured pebble-grain finish characteristic of the COXOC CO-001S design.

No blade separation, melting, deformation, or other evidence of heat-related damage was observed.		The specimen was photographed prior to cleaning and subsequently prepared for detailed documentation, testing, measurement, and teardown examination.

	The attachment plug remained particularly significant because it preserves molded COXOC branding, providing independent confirmation of manufacturer identification. The logo matches the branding documented on specimen OS-0028 and further supports attribution of the model to COXOC.

	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.		Removal of the upper housing revealed internal construction that is essentially identical to that documented within specimen OS-0028. Major components include a stamped-metal outlet-contact assembly, a RONG FENG RF-112B resettable circuit breaker, an illuminated rocker power switch, and a single SAS 241KD14 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~~.
