11-140 Terminal Blocks - Barrier Blocks are terminal blocks that are designed to provide protection against electric shock in systems where accidental contact with live wires may occur. They are used in applications where safety is paramount, such as medical or industrial settings, and in any situation where a person may come into contact with live wires or terminals.

Terminal Blocks - Barrier Blocks are made of two primary parts, a base and a barrier. The base is made up of two metal pieces connected by a single center post, which holds the terminals in place. The barrier is a plastic cover that fits over the terminals and prevents accidental contact with the terminals or wires. The barrier also protects the terminal blocks from dust, dirt, and moisture. Terminal Blocks - Barrier Blocks are typically mounted onto DIN Rails, which are typically secured with mounting screws. The DIN Rail can then be adjusted to fit the size and shape of the terminal blocks. Once the terminal block is secured to the DIN Rail, a barrier is placed over the terminals. The barrier may be formed of hard plastic or may be made of a soft material that can be slipped over the terminals. The primary function of Terminal Blocks - Barrier Blocks is to protect circuits and wires from accidental contact or connection. They are also designed to function as a means of insulating and preventing accidental contact of the user or other objects with dangerous voltages. Both the base and the barrier of a Terminal Blocks - Barrier Blocks are usually covered with a label indicating the maximum voltage and current which can safely pass through them. This label helps prevent the user from connecting to the wrong circuit due to an incorrect voltage or current. Terminal Blocks - Barrier Blocks also make connections easier and more reliable. Each connector on the base includes two contact pins which ensure a good connection even when the wires are moved due to vibration or temperature change. The terminals are also designed to be easier to access and connect, eliminating the need for tools and simplifying the connection process. Finally, the barrier can also be used as an environmental seal. The barrier blocks can be soldered to form a joint seal which will keep the connection secured and protected from moisture and outdoors elements. This seal is especially important when connecting terminals outdoors in harsh conditions.In conclusion, Terminal Blocks - Barrier Blocks are an important component in electrical systems, providing safety and ensuring reliable connections. They are designed for use in systems that may come into contact with live wires or terminals and must meet safety standards. Additionally, they are an essential component in systems that may encounter extreme temperatures, vibrations, or require high resistance to the elements.
