Features 1、Safer Working: Made of PBT flame retardant material that is sturdy with high and low temperature, which also has good mechanical strength and good insulation and will not break, deform, burn or short circuit during use. 2、Good Material: All bus bars and fuse clips are nickel plated copper for corrosion resistance and excellent electrical conductivity. 3、LED Indicator: The red LED indicator can correspond to the electrical appliances connected to each fuse strip. When the fuse is disconnected, the red light will be on, and you can immediately know which fuse is broken. 4、With Stickers: Comes with stickers, which can be attached to the electrical appliances connected according to the name on the sticker. When the fuse is broken and the red light is on, we can quickly identify which electrical appliance has a problem, saving time and effort. 5、Doubled Fuses: When in working, the fuse is burned out and can be replaced from the spare fuse immediately, and the fuse is sent with multiple amps. The fuse for amps can be selected according to the current electrical appliance. 6、Easy to Install: All fasteners are made of stainless steel, the input and output ends of the fuse box are fixed with tightening screws, which can be installed more quickly, and the fuse box is fixed with self tapping screws, which is easier and safer to install. Specification Item Type: Fuse Block Product Model: CS-664A2 Product Size: Approx. 138 x 85 x 37mm / 5.43 x 3.35 x 1.46in Product Material: PBT Body + PC Waterproof and Dustproof Cover + Nickel Plated Copper Connection Terminal + PPX40 sticker Input Rated Current: 100A Output Maximum Current: 30A Per Circuit Indicator Colour: Red Main Wire Terminal: M5 Threaded Stud Main Wire: #4-6 Single Wire Terminal: M4 Threaded Stud Single Wire: #12-16 Indicator Function: When the red LED light is on, it means that the fuse has been disconnected, and the fuse needs to be replaced in time to continue running. Product Installation Range: It can be installed on cars, villas, RVs, buses, yachts, boats, etc. Scope of Product Use: It can be directly connected to the line of any electrical appliance on the car and ship, such as dome light, car headlight, width light, fog light, warning light, car refrigerator, car charger, car fan, car TV, etc. Function of Fuse: When the circuit fails or is abnormal, the current continues to increase, and the increased current may damage some important components or valuable components in the circuit, and may also burn the circuit or even cause a fire. Fuses protect electronic equipment from over current and also protect electronic equipment from serious damage caused by internal faults. Therefore, there is a rating on each fuse, and when the current exceeds the rating, the fuse will blow. If the fuse is correctly placed in the circuit, the fuse will cut off the current by itself when the current abnormally rises to the upper limit height and upper limit temperature, thereby protecting the circuit operation.
