1. HIGH QUALITY: Pair of 12V bus bar (red and black) with screws: 6 x #8, terminals: 4 x 3/8" (M10). The busbar terminals are made of 304 stainless steel, which is less prone to rust and lasts longer than other busbar's iron terminals 2. SAFETY & DURABLE: The distribution block is nickel plated brass contact plate has low resistance, maximum conductivity and weather resistant features. Glass-filled nylon base for superior insulation and strength 3. OPERATING PARAMETERS: Battery terminals distribution block at 250A when operating on a 12v circuit, the battery distribution block can handle a maximum voltage of 48VDC and a maximum continuous current of 150ADC. Wide application: This power distribution block with cover for 12 volt bus is designed to make circuit wiring neat and tidy, preventing wiring harnesses from being messed up and causing short circuits, suitable for cars, trucks, caravans, boats and yachts, solar wiring, etc 4.UPGRADED DESIGN: The special fixing method of our marine busbar and base can withstand high torque, the whole busbar is more stable, the busbar won't shake when loosening the nut. The busbar cover can cover the exposed area to prevent accidental short circuit. The exposed areas on both sides allow 180° installation, which can meet various connection methods 5. SAFE AND RELIABLE: Each bus bar is equipped with a protective cover and two nuts, which help to cover as much exposed area as possible to minimize the risk of accidental contact, prevent short-circuiting, and make circuits safer. To work wherever you might need it, we've designed each bus bar to handle up to 300V AC, 48V DC and 250A at 12V DC . So whether you're working on a boat, a car or an RV, we've got you covered power distribution block; bus bar; distribution block; bus bar 12v; buss bar 12v; 12v bus bar; 12v power distribution block; buss bar; battery bus bar; battery distribution block; bus bar terminal block 12v; terminal block; busbar; bus bar 48v; 12v terminal block; battery terminal block; blue sea bus bar; marine power distribution block; ground bus bar; battery terminal distribution block; marine bus bar; distribution block car audio; ground bar; 12v distribution block; power distribution block car audio; 12v buss bar distribution block; distribuidor de corriente car audio; copper bus bar; bus bar 12v marine; busbars 12 volt; terminal blocks 12v; ground distribution block; grounding bar; marine terminal block; 0 gauge distribution block; ground block; marine bus bars 12v waterproof; power distribution board; buss bar 12v marine; bus bars; smd distribution block; 12 volt distribution block; car audio distribution block; junction block; automotive power distribution block; ground terminal block; negative bus bar; terminal strip; terminal blocks; victron bus bar; ground bars for electrical panels; negative bus bar 12v marine;
