Blue Sea Systems 2506 Terminal Block, 6 Circuit, 30 Amp 600V AC/DC Marine Bus Bar

The Blue Sea Systems 2506 is a 6 circuit terminal block rated for 30 amps at 600 volts AC/DC, built for organizing and distributing power connections on boats and other DC or AC electrical systems. Each pair of M4 (#8) screw terminals forms one electrically isolated circuit, so multiple independent connections can be mounted on a single block without cross-talk between circuits. The current-carrying bus is nickel-plated brass for durable, corrosion-resistant conductivity, while a closed-back housing fully insulates the live terminals from the mounting surface, allowing safe surface mounting to a panel, bulkhead, or enclosure without a separate insulating standoff.

Because each screw pair is isolated by design, the 2506 is often used simply as an organized set of independent connection points. For applications that require combining several of those isolated circuits into a common bus, Blue Sea Systems terminal block jumpers are available separately and are compatible with this terminal block as well as ST-Blade fuse blocks 5035 and 5037.

Frequently Asked Questions

How many circuits does the Blue Sea Systems 2506 terminal block have? The 2506 terminal block has 6 independent circuits, with each screw pair forming its own isolated connection point.

What is the amperage and voltage rating of the 2506 terminal block? It is rated for 30 amps at 600 volts AC/DC per circuit.

What size screws does the Blue Sea Systems 2506 use? Each terminal uses an M4 (#8) screw for making connections.

Can the circuits on the 2506 terminal block be combined into a common bus? Yes, Blue Sea Systems terminal block jumpers, sold separately, can be added to the 2506 to combine independent circuits into a common circuit.

Are the jumpers for combining circuits included with the 2506 terminal block? No, the jumpers used to combine circuits on the 2506 are sold separately and are not included in the box.

What are the dimensions of the Blue Sea Systems 2506 terminal block? The 2506 measures 4.38 x 3.94 inches (111.20 x 100.00 mm) overall.

How much does the Blue Sea Systems 2506 terminal block weigh? It weighs 0.21 pounds.

What material is the current-carrying bus on the 2506 made of? The bus material on the 2506 terminal block is nickel-plated brass for reliable, corrosion-resistant conductivity.

Is the 2506 terminal block safe to mount directly on a metal panel? Yes, the 2506 has a closed-back design that fully insulates the live power terminals from the mounting surface, so it can be surface mounted safely.

Is each circuit on the 2506 terminal block electrically isolated from the others? Yes, each screw pair on the 2506 forms one electrically isolated circuit unless jumpers are added to combine them.

What is the terminal block housing color and material? The 2506 has a beige plastic housing.

Is the Blue Sea Systems 2506 suitable for both AC and DC circuits? Yes, the 2506 is rated for 30 amps at 600 volts for both AC and DC applications.
