About this product

The Blue Sea Systems PowerBar 600A BusBar is a high-current bus bar for organizing heavy DC and AC cable connections in marine electrical systems.

It is rated for 600A DC and 545A AC continuous service, with a maximum voltage rating of 48V DC or 300V AC. The 3/8"-16 stud terminals suit large cable lugs used in battery banks, inverter feeds, windlass circuits, thrusters, charging systems, and main distribution points where clean cable routing matters.

The bus is tin-plated copper CDA 110/UNS11000 on a UL 94-V0 rated glass-reinforced thermoplastic base, giving installers a compact way to build a central positive, negative, or ground bussing point while keeping high-amperage terminations accessible for inspection and service.

Key Features

• 600A DC and 545A AC continuous rating for high-current marine distribution work.
• Maximum voltage rating of 48V DC or 300V AC for use in common marine DC systems and applicable AC distribution layouts.
• 3/8"-16 stud terminals accept large cable lugs used on battery cables and other heavy conductors.
• Tin-plated copper bus helps maintain conductivity in demanding onboard electrical environments.
• UL 94-V0 rated glass-reinforced thermoplastic base adds insulation and support for panel or bulkhead mounting.
• Terminal stud torque rating of 140 in-lb helps installers tighten connections to a defined value instead of guessing.
