1, Premium Materials & Great Conductivity: Tin-plated pure electric copper distribution block bus for max conductivity and security. High-current collecting rail is reinforced fireproof ABS base, which ensures great mechanical strength and durability. Stainless steel screws and nuts for improved corrosion and rust resistance in salt water or corrosive environments 2, Max. Currence & Voltage: The rated current of the entire electrical block is 100 A. The max. voltage is 48 V DC. The Black car power distributor usually connected to the negative pole, the Red one is connected to the positive pole 3, Ideal for Multiple Batteries Wiring Configurations: Durable collecting rails are 5x ( #8/32) Screws+ 2x ( 3/16"-24) Studs Terminals, many connecting points 4, Easy Installation: surface mount, 2 mounting holes accept #10 (M5) screws 5, Widely Fit for Vehicle, Solar and Marine Applications: The Terminal busbar is suitable for power systems such as RV, solar panel, car, truck, yacht, boat etc. to consolidate, distribute or protect your electrical system 6, Gauge Cable Fit: The threaded stud is 3/16". Gauge wire will work as long as the terminal end has a 3/16" Lug. and the combined amp draw of all connected wires do not exceed 100amps. Note: the wire and over current protection is sized based on the load. Make sure the Lug can work with 100A current 7, The Busbars are Climate Friendly. Safer Chemicals. contain Recycled Materials. Worker well-being. Economical Package Spec:
