Terminal blocks - Barrier Blocks

A 0387403718 Terminal Block barrier block are a type of electrical connection device which helps to provide a safe, secure and reliable connection between two or more electrical points or components. They can be used to divide an electrical system into multiple sections, which can be individually switched on and off. The terminal blocks or barrier blocks are designed to protect the wiring or components used in an electrical system from short-circuits, power surges, and other electrical risks. Moreover, these connectors are very easy to install and maintain.

Application Field

Terminal blocks - Barrier Blocks are used extensively in the electronics, automotive, industrial, and medical fields. In electronics, these blocks are used to connect electrical components in electronic devices such as TVs, computer monitors, DVD players, and electronic instruments such as oscilloscopes or transducers. In the automotive industry, they are used to interconnect and protect the wiring harness systems in automobiles, buses, and motorcycles. In the industrial field, these blocks are used to interconnect motors, pumps, and other electrical equipment in factories and plants. They are also used to connect several pieces of medical equipment in hospitals and clinics.

Working Principle

Terminal blocks - Barrier Blocks typically use a screw or clamping terminal. A screw terminal usually consists of two metal plates separated by a molded insulating material. The plates are connected via a threaded screw, so when the screw is tightened, the plates are pushed together to form a secure electrical connection. On the other hand, a clamping terminal uses a spring-loaded clip which locks the terminal blocks in the appropriate position when the two plates are brought into contact.

Terminal blocks - Barrier Blocks can also be made of various materials, such as plastic, copper, brass, steel, and aluminum. Depending on the material used, the blocks can be designed to have different electrical properties and strength parameters. Copper and brass terminals are typically used for low-voltage applications, while aluminum terminals are used for higher-voltage applications. Plastic terminals are typically used for electrical insulation.

There are many types of terminal blocks, such as single-pole, double-pole, and multi-pole options. The single-pole terminal blocks are usually used in low-voltage applications, while the double pole and multi-pole terminal blocks are used for higher-voltage applications. Furthermore, terminal blocks can also be used in combination with plug-in modules and terminals, allowing multiple parallel circuits to be easily connected.
