Terminal Blocks - Barrier Blocks

Barrier blocks, also known as terminal blocks or disconnect blocks, provide electrical isolation between two points. They are used to create a safe and secure electrical connection, and are typically installed in industrial control panels, agricultural machinery, laboratory and test equipment, and power generation equipment.

Barrier blocks typically consist of two parts; the base strip and the terminal strip. The base strip is a plastic housing that consists of a printed circuit board. The terminal strip has multiple metal contacts, or pins, which are used to connect wires to the base strip. The pins are secured with bolts, screws, or snaps, depending on the type of block used.

Barrier blocks come in a variety of grades, sizes, and styles, and can be used for a variety of applications. For example, they can be used in large control panels for commercial and industrial applications where high current is involved. In addition, they can be used in computer networks, telecommunications, and electronics test and measurement equipment.

Barrier blocks are well suited for industrial applications as there are no exposed pins, making them less susceptible to electrical interference. They also provide a secure electrical connection, as the terminals are held in place by the bolt, screw, or snap. Furthermore, they are easy to connect and disconnect, as the base of the block is secured to the electrical panel.

The working principle of a barrier block is quite simple. Electrical current is introduced into the block through one of the terminals. The current passes through the base strip and grounds out at the other terminal. The terminal pins are then connected to the appropriate wires to complete the electrical circuit.

Barrier blocks are an important component of any electrical system, providing an effective and efficient way of connecting electrical current. They are a reliable and safe way to connect and disconnect circuits, and are essential for most industrial, electronic, and communication applications.
