Terminal Blocks - Barrier Blocks

A 0387412720 terminal block is an assembly of metallic or non-metallic components that serves as an electrical junction, as well as for the protection of the electrical circuit from short circuits or electrical overload. It is essentially a connector that is used to connect two or more electrical wires or conductors. Typically, a terminal block is composed of a group of metal strips or bars, each of which is designed to accept a single wire. The strips are spaced apart and held together by a base plate made of plastic, steel or other material.

A barrier block, on the other hand, is a special type of terminal block that is designed to prevent cross-connection between wires. The design consists of a metal baseplate on which two or more strips of metal, each designed to receive a single wire, are placed parallel to each other. The strips are then separated by an opaque barrier, usually made of plastic, which is designed to block the passage of electrical current between strips. The strips are also usually spaced apart to prevent short circuits from occurring.

Terminal blocks and barrier blocks have multiple applications in the field of industrial electrical wiring and are primarily used for the connection of control, signal and power lines in industrial automation systems. They are used in a variety of industries, including electronics, automotive, aerospace, and military applications. The main use of terminal and barrier blocks is in the connection of electronic circuits to one another. This is achieved by connecting the electronic components to the blocks using threaded or quick disconnecting terminal connectors. The use of terminal and barrier blocks for this purpose provides a reliable and secure connection that prevents accidental disconnection of the components, allowing the circuit to function as intended.

Terminal blocks and barrier blocks also provide an effective way to protect electrical circuits from short circuiting or electrical overload. The use of barrier blocks is useful in preventing cross-connection of wires, as well as preventing the passage of electric current between terminals. They can also provide protection against electrical interference and surge currents. Additionally, these blocks can help organize electrical wiring, shorten installation time and reduce the overall size of the wiring system.

In terms of working principles, terminal and barrier blocks work together to provide connection and isolation of multiple wires. The strips on the blocks are electrically connected, and any current traveling through one of the strips is redirected to the other. The barrier blocks ensure that current cannot cross between the strips, enabling each set of wires to be electrically isolated from one another. This ensures that each electrical load is isolated from the others, preventing short circuiting and electrical overload.

Terminal and barrier blocks are necessary components for many industrial electrical wiring applications, providing reliable connection and protection of electrical circuits. They are useful in connecting components to electrical circuits, as well as preventing electrical interference and surge currents, making them a valuable tool for the industrial automation industry.
