Item Type: Fuse Block_x000D_ Product Model: CS-664A2_x000D_ Product Size: Approx. 138 x 85 x 37mm / 5.43 x 3.35 x 1.46in_x000D_ Product Material: PBT Body + PC Waterproof and Dustproof Cover + Nickel Plated Copper Connection Terminal + PPX40 sticker_x000D_ Input Rated Voltage: 32V_x000D_ Input Rated Current: 100A_x000D_ Output Maximum Current: 30A Per Circuit_x000D_ Indicator Colour: Red_x000D_ Main Wire Terminal: M5 Threaded Stud_x000D_ Main Wire: #4-6_x000D_ Single Wire Terminal: M4 Threaded Stud_x000D_ Single Wire: #12-16_x000D_ 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. _x000D_ Product Installation Range: It can be installed on cars, villas, RVs, buses, yachts, boats, etc. _x000D_ 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. _x000D_ 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.
