1.1. High Quality: One pair of 12V busbars (red and black) with screws: 6 x 8, terminals: 4 x 3/8' (M10). The busbar terminals are made of 304 stainless steel, not easy to rust, and have a longer service life than the iron terminals of other busbars 2.2. Safe and Durable: The distribution board adopts nickel-plated brass plate for low resistance, maximum conductivity and weather resistance. Glass-filled nylon base for excellent insulation and strength 3.3. Working Parameters: The battery terminal distribution board is rated at 250A when operating on a 12v circuit, and the battery distribution board can handle a maximum voltage of 48VDC and a maximum continuous current of 150ADC. Wide range of uses: This 12 volt busbar distribution board with cover is designed to make circuit wiring neat and tidy, prevent the wiring harness from being messy and causing short circuits, suitable for cars, trucks, caravans, ships and yachts, solar wiring, etc. 4. 4.D Design: Our marine busbar and base adopt a special fixing method, which can withstand high torque, the whole busbar is more stable, and the busbar will not shake when loosening the nut. The busbar cover can cover the exposed area to prevent accidental short circuit. The exposed area on both sides allows 180° installation, which can meet various connection methods.
