Busbar PowerBar1000 1990

The PowerBar1000 1990 busbar (Blue Sea Systems BS 1990) is a high-load busbar made of tin-plated, high-purity electrolytic copper for 1000 A, serving as a central connection point for large and small conductors in complex on-board networks. The stepped busbar design with two connection levels ensures significantly higher connection density than conventional busbars.

Frequently asked questions. Answered briefly.

What is the PowerBar1000 1990 suitable for?

The PowerBar1000 1990 is suitable for large, complex on-board networks where both main lines with 3/8" ring terminals and numerous smaller control and auxiliary lines are to be brought together at a single, clear collection point – for example, as a central positive or ground busbar with directly attached fuse blocks. If even higher demand arises, multiple PowerBar1000 busbars can be ganged together via the end caps.
