Barrier Blocks

Barrier blocks, also known as terminal blocks or terminal strips, are small electrical devices which act to connect wires or circuits together. They are commonly used in industrial, military and consumer electronics to provide a secure and easily accessible connection point for terminal wiring. Barrier blocks serve the purpose of creating an orderly and safe connection point for wire and circuit boards.

The 0387405403 barrier block is a multi-level 5-pin barrier block. The barrier block accepts up to 5 AWG size wire with a maximum current rating of 110A. It is designed with a mechanical terminal block with a safe voltage rating of 1000V. The block also features a large clear terminal marker window for clear and defined identification of the block with its corresponding terminals.

The construction of this block is designed with a screw terminal connection. There are two terminals per level for a total of five levels. The terminals are interconnected to each other with solid copper wire, secured with brass or nickel plated screws. The block also features a set of finger guard walls surrounding the terminals to offer additional protection from touching live connections.

The wide variety of applications for this 5-pin barrier block include industrial and commercial electrical equipment, power supply systems, control and automation systems, instrumentation and automation control wiring, and load centers. Additionally, this block is commonly used in a variety of automotive and recreational vehicle wiring projects due to its ability to withstand frequent vibration and shock.

Regardless of the application, the 0387405403 multi-level 5-pin barrier block is designed to be reliable and efficient in providing a secure connection for electrical wires or circuits. The finger guard walls help to keep users from accidentally touching any live connections. Additionally, the clear terminal marker window makes identifying the block and its corresponding terminals quick and easy, greatly increasing efficiency and safety.
