About this product

The Blue Sea Systems 2019 is a dual-stud common busbar for creating a single high-current connection point in DC systems up to 48V. It uses two 3/8"-16 studs and carries up to 200A, so it suits battery cables, charger feeds, inverter connections, and other heavy DC conductors that need a clean shared point.

The current path is tin-plated copper, and the base is glass-reinforced thermoplastic with a UL 94-V0 flame rating. That makes it a practical choice for battery compartments, consoles, machinery spaces, and other onboard areas where vibration, moisture, and salt-heavy air can work on electrical hardware over time.

This busbar is a good match when the job calls for a simple two-stud connection rather than a larger distribution block. On refits and service work, it helps tidy up cable routing and gives larger ring terminals a dedicated place to land without stacking everything on a battery post.

Key Features

• Two 3/8"-16 terminal studs sized for larger ring terminals and high-current cable runs
• 200A rating with a 48V DC maximum for battery, charging, and main DC distribution circuits
• Tin-plated copper bus for strong conductivity and better resistance to corrosion in marine electrical spaces
• Glass-reinforced thermoplastic base with UL 94-V0 flame rating
• 100 in-lb stud torque specification to help secure cable lugs correctly during installation
• Compact layout that consolidates power sources or loads into one common connection point
