BEP Pro Installer 650A 5-Stud Heavy-Duty DC Busbar

The BEP Pro Installer 777-BB5S-650 is a high-capacity, 650 A heavy-duty DC power distribution busbar equipped with five M10 (3/8 in) stainless steel studs. Engineered for high-load main DC distribution, main battery return banks, inverter/charger common feeds, and bow thruster power hubs, it provides a compact, low-resistance termination point for high-gauge battery cables (70mm²  to 120 mm²+ / 2/0 to 4/0 AWG).

As part of the modular BEP Pro Installer series, the 777-BB5S-650 features a standardized footprint and common interconnection height, allowing direct, space-saving link-up with Pro Installer battery switches, fuseholders, and power distribution hubs using solid copper Z-link busbars. Built with a high-purity tinned C11000 copper plate, stainless steel hardware, and a high-temperature reinforced plastic base with snap-out side skirt windows, it meets rigid ABYC E-11 standards for marine electrical insulation and structural integrity under severe vibration.
