Terminal Blocks - Barrier Blocks

0387107512 is a terminal block, also known as a barrier block, used in electrical engineering for making connections in electrical circuits without the risk of electrically shorting. Barrier blocks are constructed of an insulating body, and feature two metal crimp terminals to connect wires to the sides of the block. This type of terminal block is commonly used in industrial control panels such as relays and control boxes, as it provides safety and durability in electrical applications.

Barrier blocks are most commonly used in applications such as wire terminations, wiring to switches and relays, and contact bridge for electrical equipment. Their simple design make them a cost-effective and reliable connector for a variety of electrical applications. They are also widely used to connect instrumentation and mechanical equipment controlling equipment.

Application Field

Barrier blocks are used in a wide variety of electrical devices and projects. They are most often used in circuit boards and panels for user control assemblies, in industrial automation, in data entry devices, and many other devices used in industrial, aerospace, automotive, marine, medical, and military applications.

They are also perfect for connection of wire, wire harnesses, and communications and data cables with a variety of plug and socket connectors in a variety of manufacturers’ products. Since these products are designed to protect the wires, they are often rated for the environment they will be used in, such as wet or damp climates, warm and hot climates, and even explosive atmospheres.

Working Principle

Barrier blocks work on the principle of insulation between the wires and the terminal. They are connected to a terminal strip, where the conductor of the wires slide into the grooves of the terminal strip. The conductor then passes through the slots of the terminal block and the contacts are crimped making connection between two wires. The connection is strong and reliable and the insulation prevents any short circuits.

Barrier blocks feature two metal crimp terminals which fit either side of the block, allowing electrical currents to pass through them without any risks of short circuits. The insulation makes them suitable for use in any environment and also helps eliminate any problems which can occur with loose wiring.

Barrier blocks come in a variety of sizes and colors, so it is important to choose the right one for the job. They can be affixed to a panel or wall with screws, brackets, and nuts or mounted on printed circuit boards using standard fasteners.

Conclusion

Barrier blocks are ideal for use in electrical projects and are easy to install. Their simple design provides a reliable and secure connection, and their insulation ensures safety in any environment. They are also cost-effective and come in a variety of sizes and colors to fit any application.
