Terminal Blocks - Barrier Blocks

0387890020 terminal blocks are specialized devices used for the purpose of terminating electrical cables. They are designed to facilitate the secure and reliable connections of current carrying conductors while providing an effective barrier against short circuit and providing insulation.

Application Field

The 0387890020 terminal blocks are mainly used in industrial and building automation installations. They can be employed to secure electrical connections in a variety of situations, including transmission systems, electrical connections in buildings, and switchgear. These terminals blocks are also often used in combination with fuse elements, allowing for over-current protection for sensitive electrical items.

Working Principle

The 0387890020 terminal blocks operate on the standard principle of terminal blocks, which is the use of a physical contact to make a secure electrical connection. The terminal contact is made through pressure contact with the conductor, which eliminates the need for soldering, reducing installation and maintenance time. The device is then properly insulated, providing protection against electrical shock, as well as providing a reliable connection.

The 0387890020 terminal blocks come pre-wired with a combination of wiring configurations, including mechanical cross-connection, direct screw/bolt, and mechanical/electrical contact. The primary advantages of using these terminal blocks are their ability to provide a secure connection with minimal installation effort, as well as their reliable operation. Furthermore, they are designed to prevent cross-circuit short-circuiting, safeguarding sensitive electronic components from overcurrent.

Conclusion

0387890020 terminal blocks are highly reliable and heavily used devices in the industrial and commercial sector, enabling secure electrical connections that provide an effective barrier against short circuit. They come in several different wiring configurations, providing versatile solutions that are easy to install and provide reliable operation. The primary advantage of the device is the elimination of the need for soldering, allowing for quicker installation and maintenance.
