6/12 Way Waterproof Blade Fuse Block with LED Indicator & Negative Bus Bar

Keep your vehicle's electrical system organized, protected, and easy to monitor with this heavy-duty waterproof blade fuse block. Designed for cars, trucks, RVs, boats, and off-road vehicles, this power distribution panel supports 12V–32V systems and delivers up to 100A on the main line with up to 30A per individual circuit. Made in Mainland China.

Why Choose This Fuse Block?

• Flame-Retardant PBT Body: The fuse block housing is built from PBT — a flame-retardant, high/low temperature-resistant, and eco-friendly material that won't crack, deform, or short-circuit under stress.
• Nickel-Plated Bus Bars & Fuse Clips: All conductive components are nickel-plated for superior corrosion resistance and optimal electrical conductivity, even in marine and high-humidity environments.
• Steel Fasteners with Tightening Screws: Input/output terminals are secured with tightening screws for a fast, reliable installation. The box itself mounts via self-tapping screws for a solid, vibration-resistant fit.
• Red LED Fault Indicators: Each fuse circuit has a dedicated red LED that lights up the moment that fuse blows — so you instantly know which circuit needs attention without guessing or using a multimeter.
• Labeled Sticker Sheet Included: Attach the included stickers to identify each circuit by connected appliance. When the LED lights up, you'll know exactly which device has an issue — saving you time and frustration.
• Dual Fuse Supply: Comes pre-loaded with a full set of spare fuses (5A, 10A, 15A, 20A) so you can swap a blown fuse on the spot and get back on the road or water immediately.
• Damp-Proof PC Cover: The dust- and moisture-resistant polycarbonate cover keeps your circuits protected from splashes, condensation, and road grime — ideal for engine bays, bilges, and outdoor enclosures.

Frequently Asked Questions

Q: What is the maximum voltage and current this waterproof fuse block supports?

A: This blade fuse block supports input voltages from 12V to 32V DC, making it compatible with standard automotive (12V) and heavy-duty truck or marine (24V/32V) systems. The main line is rated for up to 100A, with a maximum of 30A per individual circuit.

Q: How do the LED indicators on this fuse block work?

A: Each circuit has a dedicated red LED indicator. When a fuse in that circuit blows, the LED illuminates, immediately showing you which circuit needs a replacement fuse — no guesswork, no multimeter needed. Simply replace the blown fuse with one of the included spares.

Q: Is this fuse box truly waterproof and suitable for marine or outdoor use?

A: Yes. The fuse block features a damp-proof polycarbonate (PC) cover that protects against moisture, splashes, and dust — making it well-suited for boats, marine applications, outdoor installations, and engine bays exposed to the elements.

Q: What size fuses does this fuse block use, and are they included?

A: This fuse block uses standard blade-type fuses. Both the 6-way and 12-way versions include an assortment of 5A, 10A, 15A, and 20A fuses in the box. The fuse rating per circuit can be selected based on the current requirements of each connected device.
