Blue Sea Systems PowerBar 600A BusBar, 4x 3/8-16 Terminal Studs (2104)

The Blue Sea Systems PowerBar 2104 is a 600 amp DC power distribution busbar built for high-current marine electrical systems. It carries a continuous rating of 600A DC (545A AC) with a maximum voltage of 300 VAC / 48 VDC, making it suited for distributing power from a battery or main power source to multiple circuits from a single, low-resistance point. The busbar mounts on a reinforced polycarbonate base and uses a tin-plated pure electrical copper conductor (CDA 110/UNS11000) for maximum conductivity, with four 3/8"-16 terminal studs for heavy cable connections and four #8-32 stainless steel screws with captive lock washers for securing smaller gauge wires.

The busbar and fuse block elevations are matched to common fuse blocks, allowing multiple fuse blocks to be attached directly without extra connecting cables. One-piece serrated flange nuts ensure correct, secure terminal connections, and the busbar can be cut to a shorter length to fit constricted installation spaces. Bi-directional busbar end caps allow additional busbars to be ganged together for larger systems. An insulating cover that meets ABYC and USCG requirements is available separately as part number 2708.
