Name: Fuse Box Model: ZH-978A2Net weight: about 297GGross weight: about 303GSize: about 195 * 50 * 52mm/7.68*1.97*2.05inMaterial: PA66 body, PC dust cover, nickel-plated copper terminal, stainless steel screw, PP × 70 stickerInput rated voltage: 32VInput rated current: 75AMaximum output current: 20A per circuitMain wire terminal: M6 threaded stud (75A 32V DC max)Main wire lead: # 4-6AWGSingle wire terminal: M4 threaded stud (20A, 32V, DC max)Single wire: # 12-16AWGFuse type: accept ATO or ATC fuse from 1A to 20AInstallation range: can be installed on cars, villas, RVs, buses, yachts, boats, etc.Scope of use: can be directly connected to the wire of any electrical appliances on the car or ship. Such as: car ceiling lights, car headlights, sight width lights, fog lights, warning lights, on-board refrigerator, on-board charger, on-board fan, on-board TV, etc.Fuse function: When the circuit is faulty or abnormal, the current is constantly increasing, and the increased current may damage some important or valuable components in the circuit, and it may also burn the circuit or even cause a fire. The fuse protects the electronic equipment from being damaged by over-current, and can also avoid the serious injury caused by the internal failure of the electronic equipment. Therefore, each fuse has a rated specification. When the current exceeds the rated specification, the fuse will blow. If the fuse is correctly placed in the circuit, the fuse will automatically cut off the current when the current abnormally rises to a certain height and temperature, thereby protecting the safe operation of the circuit.Advantages: 1. The fuse holder are made of PA66 flame retardant and high temperature and low temperature environmental protection materials, which fully meets the requirements. The fuse holders must have good mechanical strength, insulation, heat resistance and flame resistance, and shou
