WUPP 12 Volt Fuse Block, Waterproof Boat Fuse Panel with LED Warning Indicator Damp-Proof Cover, 6 Circuits with Negative Bus Fuse Box for Car Marine RV Truck DC 12-24V

QUICK FIX: When the current or voltage exceeds the rated limits, the fuse will automatically blow. Each load is equipped with an LED indicator to signal whether a circuit has shorted or if the fuse has blown, allowing for easy identification and replacement. However, it is important to note that there may still be voltage present across the circuit even in the absence of a fuse; this occurs because the fuse box contains its own lighting circuit, which introduces resistance and consequently displays some voltage.
ENSURE NEAT WIRING: Rather than cluttering your battery terminals with a tangle of wires and fuse holders, the WUPP 12-volt fuse block and ground bus kit provides six dedicated fuses and six grounding points to maintain an organized, clean, and easily accessible wiring system. This simplifies the process of wiring electronics in your vehicle or boat.
UNIVERSAL PROTECTION: The input rated voltage of the fuse box is 32V,and the input rated current is 100A.Each circuit outputs a maximum current of 30A. All bus bars and fuse pieces are nickel-plated copper, corrosion-resistant and highly conductive.
SAFE MATERIAL: PBT flame retardant material base,good mechanical strength and high temperature resistance. It is insulated, heat resistant and flame resistant. There will hardly cause any issue like produce fracture, deformation, combustion or short circuit phenomenon.
FREE BLADE FUSES: 6-Way Package includes: 20A Fuse*4, 15A Fuse*4, 10A Fuse*2, 5A Fuse*2, Labels*2, Screws*4
