Feature:1. Strong Construction: The fuse and relay box is made of PC material, which has excellent electrical insulation, extensibility, stability and wide range of use, and the fuse holder has good mechanical strength, heat resistance and flame retardancy.2. 20A High Output: By taking power directly from the main power supply, it can reduce the burden of original electrical equipment and increase the output at the same time.3. Effective Protection: If the fuse is correctly placed in the circuit, the fuse will blow itself to cut off the current when the current rises abnormally to the upper height and temperature, thus protecting the circuit operation.4. Practical and Efficient: Our fuse and relay box can be connected to the car 4 way electrical wiring, so that the wiring is more simple and convenient, and the line is no longer cluttered, effectively preventing safety hazards.5. LED Indicator Design: The LED indicator corresponds to each fuse connected to the electrical appliances, when the line is in normal operation, the indicator light is blue; when the fuse is disconnected, the red light will on, then you can immediately know which fuse is broken, to facilitate timely processing.Specification:.Item Type: 4 Way Fuse and Relay BoxInput Voltage: 12VOutput Current: Maximum 20AIndicator Color: Blue, RedIndicator Role: When the blue LED lights up, it means the line is energized and running normally. When the red LED lights up, that means the fuse has been broken, you need to replace the fuse in timeInstallation Range: Suitable for motorcycle, car, truck, RV, 12V electric vehicleUse Range: Can be directly connected to the line of the car with electrical appliances (such as: headlights, navigation, cell phone bracket, charger, etc.)Package List:1 x Junction Box Body2 x Ribbon 1 x Round Terminal Connection Wire1 x 3A Fuse1 x 2A Fuse3 x Boat Type Wiring Clips1 x Instruction Manual
