Terminal Blocks - Barrier Blocks

Barrier Blocks are a type of terminal block specifically designed to allow two or more circuits to be isolated from one another. They are commonly used in industrial applications which require different electrical systems to be kept separate, while still sharing the same junction points. Barrier blocks provide a secure and reliable way of doing this. In addition to providing electrical isolation, they also offer relatively simple installation and a wide range of accessories to aid in making installation and maintenance easier.

Barrier Blocks come in a variety of sizes and configurations to suit different applications. The basic type consists of two or more rows of terminal strips, often with the terminals arranged in a 45 degree pattern. The number of terminals that can be accommodated depends on the size of block being used. Many blocks also have insulation sleeves fitted to the contacts to prevent accidental arcing or sparking.

The design of the Barrier Block allows it to be used in many different environments. It can be used in dry and wet locations, high temperature areas and those with hazardous atmospheres. The terminals are usually made from non-conductive material and can be insulated using a variety of materials. This allows the block to be used even in areas where there is a higher risk of exposure to electrical hazards.

Barrier Blocks are connected using wires or cables. These are usually of sufficient size and gauge to carry the amount of current required. The terminals themselves are usually designed to accept a range of wire types and sizes, allowing for greater flexibility when connecting different circuits. In addition, the terminals are also available in a variety of crimp or screw type connections, allowing them to be easily connected to a range of other components in the system.

Beyond the standard Barrier Block there are a number of specialised blocks available which are suited to particular applications. These can include blocks designed for high temperature use, blocks with additional features such as light emitting diodes and even blocks with integrated circuit components.

The working principle of a Barrier Block is quite simple. The terminals on the block create physical contact between the different circuits, thereby allowing the various elements of the system to be safely kept apart. In addition, the insulation sleeved terminals provide an extra layer of protection from electrical shock and sparking. The block therefore creates a safe and reliable connection point for the various systems, while still allowing them to retain their independence.

Barrier Blocks are the perfect choice for many industrial applications. They are simple to install, provide excellent insulation between components, and offer great flexibility when connecting various circuits. Whether it is in a dry, wet or high temperature environment, the Barrier Block is the ideal choice for keeping circuits separated. And with the range of options available, it is easy to find the perfect solution for any application.
