Auto Fuse Kit Automotive Plug-in Fuse 1-50A for Cigarette Lighter 4s Shop Electric Vehicle Motorcycle

This is a standard medium-size automotive blade plug-in fuse, with transparent color-coded plastic housing and zinc alloy melt wire inside. Different transparent shell colors correspond to different rated current specifications (1A–50A). It serves as overcurrent short-circuit protection for vehicle electrical circuits, widely applied to car cigarette lighter, dashboard instruments, EV control circuits, motorcycle lighting & ignition systems, truck electrical modules and auto 4S maintenance repair kits. When circuit overload or short-circuit occurs, the internal alloy melt wire instantly fuses to cut off power, effectively protecting automotive ECU, wiring harness, lamps and electrical components from burnout damage. The transparent colored shell allows visual inspection of blown fuse status without disassembly. Standard blade pin size fits all mainstream automotive fuse holders, fully RoHS compliant, complete current range 1A, 3A, 5A, 7.5A, 10A, 15A, 20A, 25A, 30A, 35A, 40A, 50A, sold separately or assembled into mixed current fuse kit boxes for auto repair shops.

Auto Fuse Automotive Plug-in Fuse color coded transparent car fuse car circuit safety fuse

Product Description

Color-coded transparent shell design enables maintenance technicians to quickly distinguish current ratings and check blown fuses at a glance, greatly improving vehicle fault repair efficiency in 4S shops and repair garages. Standard medium blade universal size fits almost all fuel vehicles, new energy electric vehicles and two-wheeled motorcycles on the market, one product covers most vehicle maintenance replacement demands. Precision alloy melt wire features accurate overload fusing characteristics, effectively prevent expensive vehicle ECU, navigation, cigarette lighter and lamp circuit burnout caused by short-circuit or overload current. High-temperature resistant PC plastic shell adapts harsh engine compartment working environments of -40℃ ~ +125℃, no deformation or cracking after long-term engine heat radiation. Complete full current range from 1A to 50A covers weak signal instrument circuits and high-power electrical equipment (air conditioning, cooling fan, cigarette lighter) protection needs of all vehicle electrical systems.

Every automotive blade fuse passes strict factory safety testing before shipment, including overload fusing characteristic test, high-low temperature cycling aging test, insulation withstand voltage test and vibration fatigue screening. We supply single current loose fuses and mixed current assembly fuse kit boxes for auto parts wholesalers, 4S service stations, electric vehicle manufacturers and motorcycle accessory factories.

FAQ

Q1: What is the difference between medium size blade fuse and mini small car fuse?

A: Medium standard blade fuse has wider blade pins and larger current carrying range (up to 50A), mostly used for main power circuits such as cigarette lighter, cooling fan and air conditioner; mini small fuses are smaller, only for weak signal instrument circuits below 15A.

Q2: How to quickly judge whether the car fuse is blown?

A: This product adopts fully transparent colored plastic housing, you can directly observe the internal alloy melt wire through the shell; if the middle melt wire is disconnected, the fuse is blown and needs replacement.

Q3: Can this medium fuse be used for electric motorcycle and new energy vehicle circuits?

A: Yes, rated DC 32V matches most EV and motorcycle low-voltage auxiliary electrical systems, suitable for instrument, lighting and charging signal circuit overcurrent protection.

Q4: Is it allowed to replace a blown fuse with a higher current specification?

A: Strictly prohibited. Must replace with the same rated current fuse as the original factory specification; using a larger current fuse will lose protection function, easily cause vehicle wiring harness overheating and fire hazards.

Q5: Can we customize mixed current combination fuse kits for auto repair shops?

A: Fully supported, we can assemble different proportion mixed current fuse storage kits, and match plastic fuse puller removal tools as complete maintenance spare parts sets.
