[Product Advantages]: [1] The product is made of PA66 flame-retardant material with high and low temperature resistance, offering excellent mechanical strength, insulation, heat resistance, and flame resistance. It will not break, deform, burn, or cause short circuits under normal operating conditions. [2] All fasteners are constructed from stainless steel. The input and output terminals of the fuse box are secured with tightening screws for quick installation, while self-tapping screws are used to mount the fuse box, ensuring a safer and more convenient setup. [3] The product includes labeled stickers that can be affixed to connected electrical devices. In the event of a blown fuse, users can quickly identify the affected device, saving time during troubleshooting. [4] The kit comes with multiple spare fuses. When a fuse blows, it can be immediately replaced with an included backup. Fuses are provided in various amperages, allowing selection based on the specific electrical load. [Product Model] ZH-979A2 [Input Rated Voltage] 32V [Input Rated Current] 75A [Maximum Output Current] 20A per circuit [Material] PA66 body, PC dust cover, nickel-plated copper terminals, stainless steel screws, PP70 stickers [Single Wire Terminal] M4 threaded stud (20A 32V DC max) [Wire Specifications] #12-16AWG Accepts ATO or ATC fuses from 1A to 20A [Installation Range] Suitable for installation in cars, off-road vehicles, RVs, buses, yachts, and boats [Scope of Use] Can be directly connected to any automotive or marine electrical device such as dome lights, headlights, sidelights, fog lights, warning lights, car refrigerators, chargers, fans, TVs, etc. [Product Accessories] Sticker x2; Self-tapping screw x4; 20A fuse x2; 10A fuse x4; 5A fuse x8; 3A fuse x10 [Fuse Function] In the event of a circuit malfunction or abnormal current increase, the fuse interrupts the circuit when current exceeds its rated value. This prevents damage to critical components, protects against circuit overload, and helps avoid fire hazards, ensuring safe operation of electrical systems.
