0387109216

Terminal blocks with part number 0387109216 are generally classified as barrier blocks. These terminal blocks are specifically designed to provide protection to circuits against reactive and transient current, as well as safeguarding against electrical arcing. As an electrical terminal device, they provide electrical connectivity that ensures stability and reliability of the electrical connection.

Barrier blocks are primarily used in power distribution applications, wherein a protected connection must be established between power circuits. They are also used in telecommunications equipment to provide protection between the power source and the equipment. The terminal blocks provide secure and durable electrical paths between dissimilar metals that prevent corrosion.

Unlike standard terminal blocks, barrier blocks include a barrier component that electrically isolates each set of terminals. This feature functions as an integrated circuit protection device, and helps to reduce the risks of potential shock due to short circuit conditions. Most barrier blocks also include an outer casing that adds a layer of protection against mechanical and environmental damage, prolonging the life of the terminal block.

The working principle of 0387109216 terminal blocks is based on the principle of a break-before-make contact. When actuated, the terminals of a barrier block open their current path and then establish the new one in a sequential manner. This process creates a reliable electrical interconnection, while preventing arcing or electrical shock. Additionally, the built-in V-shaped wedge makes it easier to attach wires to the terminal block, while ensuring secure and reliable electrical connections.

In summary, 0387109216 terminal blocks are an important safety component, providing protection against common electrical dangers. These terminal blocks make electrical interconnections stable, secure, and reliable, and are used in a wide variety of power distribution applications.
