Tackle heavy-duty marine and RV electrical routing with the absolute gold standard in high-amperage power distribution. The Blue Sea Systems 600A PowerBar features eight heavy-duty 3/8" studs designed to consolidate massive power cables and high-demand circuits safely and securely. Engineered with a tin-plated pure copper bus and a heat-resistant reinforced base, it delivers uncompromised conductivity and corrosion resistance in the harshest environments.

When you are building or upgrading a complex electrical system—whether it’s a marine house bank, a multi-battery RV setup, or an off-grid solar array—the point of distribution is your most critical link. The Blue Sea Systems PowerBar 600A (PN 2107) is purpose-built to handle massive electrical loads without breaking a sweat.

Equipped with eight heavy-duty 3/8"-16 terminal studs, this heavy-duty busbar allows you to aggregate or distribute power from high-draw components like inverters, windlasses, and large battery banks.Under the hood, a continuous tin-plated copper CDA 110 busbar ensures maximum conductivity while fighting off the aggressive corrosion of marine environments.

The structural foundation is just as tough. Molded from a glass-reinforced thermoplastic that meets UL 94-V0 flammability ratings, the base offers exceptional heat resistance and robust physical isolation.Additionally, each end features two smaller screw terminals to neatly secure lower-gauge accessory wires right at the primary connection point.

Key Features

• Massive 600A Capacity: Rated for a continuous 600A DC (545A AC) to comfortably manage large-scale power distribution systems.

• Premium Tin-Plated Copper: Utilizes highly conductive CDA 110/UNS11000 copper, heavily tin-plated to resist oxidation and marine rust.

• Eight 3/8"-16 Studs: High-torque terminal studs allow for heavy-gauge cable lugs to be stacked securely (recommended up to 4 terminals per stud per ABYC standards).

• Industrial-Grade Isolation: Base made from UL 94-V0 glass-reinforced thermoplastic handles extreme engine bay or utility locker heat without warping or shorting.

• Auxiliary Connections: Includes two smaller screw terminals on each end for clean, integrated routing of minor accessory wires.
