Automotive Waterproof Blade Fuse Holder Harness (With Cover)

 Core Features

1. Waterproof & Dustproof Design: Equipped with a rubber protective cover with lanyard to fully enclose the fuse compartment. It reaches IP65 protection rating and resists rain, dust and oil contamination for safe outdoor use.
2. Compatible with Standard Blade Fuses: Fits regular standard and mini automotive blade fuses with current ratings ranging from 5A to 30A. Easy replacement and routine maintenance.
3. High-Safety Flame-Retardant Material: The housing is made of flame-retardant and high-temperature resistant ABS material, non-flammable and anti-aging. It works stably within a wide temperature range of -40℃ to +105℃, suitable for high-temperature areas such as engine bays.
4. High-Conductivity & Low-Loss Cable: Conductors are made of solid copper or tinned copper, paired with PVC/TPE insulation sheath with excellent dielectric performance. The cable features high conductivity, low heat generation, strong anti-oxidation and anti-aging properties for longer service life.
5. Two Terminal Options: Available in two versions: bare wire outlet (crimpable with terminals on demand) and pre-fitted ring terminals. It suits various installation points such as battery posts and terminal blocks for flexible wiring.
6. Tool-Free & Solder-Free Installation: Adopts pre-crimped integrated molding process for direct wiring upon receipt. Compatible with wire gauges from 12AWG to 22AWG, matching circuit systems of different power levels easily.

Product Advantages

• Comprehensive Safety Protection: Multi-layer protection including waterproofing, dustproofing, flame retardancy, temperature resistance and overload prevention eliminates potential hazards such as short circuits and fire risks for vehicle circuits.

 FAQ

Q1: Can this fuse holder be used on 24V trucks?

A: Yes. It supports wide DC voltage range from 12V to 24V and fits the 24V circuit system of most trucks and coaches. Simply select a fuse with proper current rating according to device power.

Q2: Is it fully rainproof after the cover is closed?

A: When the cover is fully fastened, the protection level reaches IP65, which can withstand splashing water and regular rainfall. It is not suitable for long-term full immersion in water. Choose dedicated fully waterproof sealed fuse holders for underwater applications.

Q3: How to select wire gauge? What is its relation with current?

A: The thicker the wire (smaller AWG number), the higher current it can carry. Recommended matching: 18AWG ≤10A, 16AWG ≤15A, 14AWG ≤20A, 12AWG ≤30A. Select the proper wire gauge based on the rated current of your device to avoid cable overheating and aging.

Q4: Can I customize cable length, terminals and wire color?

A: OEM & ODM customization is available. We can adjust cable length, wire gauge and color, replace terminal types (e.g. female quick disconnect terminals), and customize marked wire tubes to meet diverse installation requirements.

Q5: How to replace a blown fuse?

A: Open the waterproof cover, pull out the blown fuse and install a new blade fuse of the same rating. No wire disassembly is needed. The replacement is quick and will not affect the original wiring structure.
