Terminal Blocks - Barrier Blocks

562112220 terminal blocks, commonly known as barrier blocks, are an integral part of electrical service and maintenance. They help to keep electrical systems safe from shock and electrical fires due to loose connections or loose wires. They are available in different configurations and make working with and installing electrical systems easier.

Application Field

Barrier blocks are commonly used in any electrical circuit and unit that needs to be protected from shorts or loose connections. This includes computers, factory automation systems, and industrial control panels. They can also be used for larger systems such as elevators, water systems, and HVAC systems. Generally, anywhere a circuit board will need a connection to another system, a barrier block will be the most suitable choice.

Barrier blocks are particularly useful in situations where there are numerous connections to be made. It is much easier to use a few barrier blocks to make connections rather than using individual wires for each connection. This also eliminates the need for large numbers of crimped connections which can be time consuming and difficult to keep track of.

Working Principle

Barrier blocks consist of an insulation panel with a series of metal contacts attached to it. The contacts are arranged in vertical columns which are usually numbered. Each contact has a threaded post that is used to connect an individual wire to it. When the wires are connected, the barrier blocks form a reliable electrical connection.

The panels of the barrier blocks are made from a high insulation material which offers an effective barrier to electrical shock. The shielding of each individual contact helps to reduce the risk of a short circuit or loose connection. It is also possible to use barrier blocks with a locking cover which further reduces the risk of accidental disconnection.

Barrier blocks are designed to make the installation and maintenance of an electrical system safer and simpler. They can be used to replace individual wires and components which helps to create a neater and more efficient electrical circuit. By using barrier blocks to make connections, the risk of an electrical shock or fire is greatly reduced.
