Terminal blocks, also known as barrier blocks, are electrical components that are used to connect two or more electrically conductive wires or cables. They are generally used to terminate and join wires in electrical circuits, as well as to provide physical isolation between the conductive elements.
These devices are typically composed of a base and two or more posts. Depending on the particular application, they may be made of various materials such as metal, plastic, or polycarbonate. They may also feature various accessories such as fuse holders, DIN rail clips, ground terminals, and screw locks. The number of posts, their size, and configuration can vary, depending on the specific device.
The 0387700221 terminal block is a popular model manufactured by Phoenix Contact. This particular device is designed for quick and reliable connection of conductors with cross sections from 0.2 to 1 mm². It is equipped with 14 pneumatic connection points, and features a quick-connect bridge to enable fast and secure wire connection. It also has a large, easy-to-use operating lever that ensures reliable contact with the conductor. Its body is made of nickel-plated zinc die-cast, and it comes with terminals featuring a UL 94V-0 flame-retardant casing for safe and secure operation.
The terminal block’s working principle is quite simple. When the lever is raised, it opens up the electrical path between two opposing terminals, allowing an electrical current to flow between the two points. When the lever is released, the electrical path is closed again, cutting off the current flow. This allows for easy and reliable connection and disconnection of electrical circuits. They can also provide protection from short-circuits and other accidental electrical issues.
Terminal blocks are widely used in a variety of applications, ranging from household wiring to industrial machinery and equipment. They are often used to provide secure and reliable connections in motor control centers, automation systems, solar panel installations, and much more. Their simple and reliable design makes them an excellent choice for virtually any application where a safe and reliable electrical connection is required.
