Terminal Blocks - Barrier Blocks

0387690220 Terminal Blocks are specifically designed for electrical applications. They are among the most versatile and common types of electrical components, highly engineered for reliable and efficient use in various electrical systems.

These terminal blocks are specially designed to separate power supply from load and enable safe and reliable power distribution. They use a technique known as \'barrier blocks\' where insulated barriers within the terminal blocks provide a physical and electrical separation of power supply from load. This technique provides several noteworthy advantages such as a low switching cost, safer handling of current during installation, and simplifying testing and troubleshooting.

The function of the Barrier blocks is to help protect the users and operators of electrical systems from the risk of electrical shock from short circuits and overloading, and from potential laser light hazards. Barrier blocks reduce the likelihood of damage to components and equipment present in the system due to excessive voltage or current flow. They can also provide insulation between power supply and load, thus allowing multiple sources to be connected to the same load.

The design of barrier blocks depends on the type of power supply into which the blocks need to be connected. In some cases, terminals may be permanently mounted on the boards of the power supplies (directly) and in others, they may be separate components that need to be connected to the power supply by means of a connector. The physical installation of the blocks is not complicated and they can be attached to the circuit board of the power supply by means of terminal blocks, plugs, wires, screws, or solder connections.

The technical working principle of Barrier blocks is simple. In a series configuration, the current flows through each of the contacts in the block, providing the necessary insulation between the contacts. As the current flows through the contacts, it transfers the required electrical energy and voltage to the device which needs power. This electrical transfer from the power source to the device is what makes barrier blocks such an important component in electrical systems.

Barrier blocks provide the electrical connection between power supplies and the electronic components in an electrical system. By providing insulation between the two electrical components in the system, they increase reliability and safety. In addition to this, they also reduce the risk of electrical shock, thus increasing the safety and reliability of the overall system.

There are several types of Terminal Blocks available and it is important to select the type and model that best meets the specific needs of your application. Generally, barrier blocks are preferred for more demanding or hazardous applications due to their high isolation properties and low switching cost. They are also widely used in home electrical applications where safety is of utmost importance.
