Import Auto Fuse Holer — Buy in Bulk from Supplier in China

The auto fuse holder from China Ningbo Beta Enterprise Co., Ltd. accommodates input cable sizes of 0/2/4 gauge AWG and output sizes of 2/4/8 gauge AWG, with a current rating spanning 30 to 300 amperes. This range covers primary battery-to-distribution applications through to branch circuit protection in automotive, marine, and industrial equipment. The holder body uses nylon 66 or equivalent engineering polymer with a typical melting point above 260°C, maintaining structural integrity at continuous operating temperatures up to 150°C. Terminal contact resistance should remain below 0.5 mΩ at rated current to prevent parasitic heating and voltage drop across the connection.

Construction typically features tin-plated brass or copper alloy terminals with nickel underplating for corrosion resistance in salt spray environments, meeting standard automotive requirements of 48-96 hours neutral salt spray per ASTM B117. The fuse element interface accepts standard AFS, ANL, or blade-type fuses depending on specific variant, with clear polycarbonate or ABS covers providing visual fuse status inspection without disassembly. Threaded terminal blocks with M6 or M8 stud sizes are common for higher current ratings, while lower amperage variants may use screw-clamp or compression terminals. Insulation resistance between live parts and mounting surface should exceed 100 MΩ at 500 VDC per standard automotive electrical accessory testing.

Primary buyers include car audio installers, aftermarket automotive accessory distributors, marine electrical fitters, and industrial equipment OEMs requiring modular circuit protection. The 30-300A range serves starter motor circuits, high-power audio amplifiers, winch installations, and auxiliary battery systems. For trade terms, confirm with China Ningbo Beta Enterprise Co., Ltd. whether the quoted ampere rating refers to continuous or intermittent duty, as fuse holder thermal performance derates significantly in enclosed engine bays or poorly ventilated compartments. Verify whether the blister card packaging shown in typical listings is standard for export bulk orders, or if alternative carton quantities apply for volume procurement.

China Ningbo Beta Enterprise Co., Ltd. maintains its registered address at Room C1006, Century Plaza, No. 8 Hualou Street, Ningbo, Zhejiang Province, postal code 315010. The company holds imported supplier tier and harbour trust classification on the marketplace, with zero recorded response rate and no average response time data currently visible. This absence of engagement metrics suggests buyers should establish direct communication early in the sourcing process, rather than relying solely on platform messaging for quotations or technical clarifications.

The listing positions China Ningbo Beta Enterprise as a supplier of automotive electrical accessories, specifically fuse holders for power distribution applications. No manufacturing scope details, factory certifications, or years in operation are provided in the available profile. Ningbo's established electronics and auto parts manufacturing base offers supplier access advantages, though this does not independently verify production capability. Buyers should request company registration documents, scope of business certificates, and evidence of in-house tooling or assembly capability. The Century Plaza address indicates commercial office presence rather than manufacturing facility, so clarification of actual production location and whether this is a trading office or factory direct seller is advisable before committing to volume orders.
