Terminal Blocks - Barrier Blocks

0387298443 is a type of terminal blocks that belong to the barrier blocks variety. They are electronic components used to secure and assemble wires, cables, and other electrical connections in an easy and efficient manner. They can be composed of several components such as bases, barriers, contact blocks, and covers.

Application Field

Barrier blocks are typically used in industrial control systems, production line equipment, and communication systems. They can also be used in commercial and residential applications as well. Being easy to assemble and disassemble, they are generally employed in scenarios where frequent wiring changes need to take place to accommodate different functions and operations. They can also form part of a mechanical protective system in certain machine level applications.

Working Principle

Barrier blocks employ the same principle as conventional terminal blocks but their complexity varies in order to comfortably accommodate the needs of different applications. Typically, barrier blocks are composed of two parts: a base and a top. The base consists of one or several poles (also depending on the application’s needs) and the top is a U-shaped cover that is meant to securely hold wires and cables in place. The contact blocks are attached to the base by a clip or screw and usually offer a variety post-type connections.

Barrier blocks are able to accommodate different electrical current formats such as DC, AC, and pulse current. Depending on its categorization, a single block can be able to support up to 40 A in direct current, 50 A in alternating current, and 75 A in pulse current applications.

Barrier blocks are available in several sizes and post sizes, from the standard 0.2 x 0.4 inches to more complex 6 x 15 inches blocks. As mentioned, bars that secure the signals and wires into place are typically employed, though some manufacturers also offer models with a self-inserting mechanism.

Although commonly used in simple installations, barrier blocks can also be used on complex wiring mounts due to their variable number of poles. This allows for users to combine several blocks together in order to expand the connection matrix of a given system. To do so, combinations of jumper wires and blocks can be employed to provide an effective method of connection transfer.
