Blue Sea Circuit Components

Battery Selector Switches

Our 2-bank selector switch is smaller than a standard switch, yet handles more current. Features Battery 1, 2, both & off positions with full 360 degree switch rotation.

The On/Off master switch is used for controlling a single battery bank.

The BS-3000, a new heavy duty master On/Off switch capable of 550 amps is a perfect battery disconnect for large inverters, or large diesel engines. 

Heavy Duty Busbars

Use these tin-plated brass positive busbars to consolidate multiple negative wires, to create a positive busbar or for feeding multiple circuits. Screw type, stud type and dual busbars are described below.

Power Posts

Power Posts allow a number of cables to branch out from a central positive connection, or a number of negative return cables to be consolidated into a single point. Join 2 cable runs or tap into existing runs to create a new branch circuit.

600A Power Bars

Use these multiple post, 600 amp busbars when a single power post just isn't enough. Power Bars are fabricated from a solid block of tinned copper with either four or eight 3/8" studs. They accommodate even the large ring terminals used on 4/0 cable.

Power Distribution & Splicer Blocks 

Power distribution blocks split primary power into secondary circuits, or join multiple cables from a solar array to a common power lead-in cable.

Splicer blocks connect two wires of the same size, or of different sizes together.

Proudly designed & built in the USA !
