Fuse function 1. When the circuit breaks down or is abnormal, the current continues to rise, and the increased current may damage some important or valuable components in the circuit, or even destroy the circuit or even cause a fire. 2. The fuse protects the electronic equipment from overcurrent damage, and can also avoid serious damage caused by the internal failure of the electronic equipment. 3. Therefore, each fuse has a rated specification, and the fuse will blow when the current exceeds the rated specification. 4. If the fuse is correctly installed in the circuit, then the fuse will fuse itself and cut off the current when the current rises to a certain temperature abnormally, thereby protecting the safe operation of the circuit 12 Ways Fuse Box: Product net weight: 177g Product size: 115*85*18mm product material: PBT body, PC waterproof and dustproof cover, nickel-plated copper connector, PPX40 sticker Input rated voltage: 32V Input rated current: 100A Output maximum current: each circuit is 30A Main thread terminal: M5 threaded stud Single thread terminal: M4 threaded stud indicator light: when the red LED light is on, it means the fuse has been disconnected, and it needs to be replaced in time to continue running scope of product installation: it can be used on cars, houses, RVS, buses, yachts, boats, etc product accessories: sticker X1; Self-tapping screw X4; 20A fuse X6; 15A fuse X6; 10A fuse X6; 5A fuse X6 6 Ways Fuse Box: Product net weight: 106g product size: 85*70*18mm product material: PBT body, PC waterproof and dustproof cover, nickel-plated copper connector, PPX40 sticker Input rated voltage: 32V Input rated current: 100A Output maximum current: each circuit is 30A Main thread terminal: M5 threaded stud Single thread terminal: M4 threaded stud indicator light: when the red LED light is on, it means the fuse has been disconnected, and it needs to be replaced in time to continue running scope of product installation: it can be used on cars, houses, RVS, buses, yachts, boats, etc product accessories: sticker X1; Self-tapping screw X4; 20A fuse X4; 15A fuse X4; 10A fuse X2; 5A fuseX2 Product advantages : 1.the product adopts PBT anti-fire material 2.all bus and fuse clips are nickel-plated copper with corrosion resistance 3.all fasteners are stainless steel.
