Terminal Blocks - Barrier Blocks

430703-20-0 is a type of terminal block and barrier block consisting of an insulating plastic sleeve that contains multiple interconnected terminals. The sleeve is designed to provide electrical insulation and secure mechanical connection of two or more wires in an electrical circuit. Barrier blocks are used in a variety of industrial applications, from automotive to large manufacturing operations. They provide an easy and cost-effective method to manufacturer and maintain electrical wiring in an industrial environment.

Application Field

430703-20-0 terminal blocks and barrier blocks are used in many industrial applications. For example, they are often used in manufacturing and production plants to connect electrical wires, terminals, toggle switches, meters, indicators, and other assembly components. In addition, they provide a secure and reliable connection that is safe and durable. Terminal blocks and barrier blocks are also used in automotive systems, industrial and agricultural locations, instrumentation and control systems, electronic consoles, monitors, and in other settings that require reliable and secure electrical connections.

Working Principle

The working principle of the 430703-20-0 terminal block and barrier block is fairly simple. The terminal block consists of two parts: the body and the contact elements. The contact elements are connected internally, but separated by insulation material. This insulation material is designed to provide a high electrical isolation to avoid short circuits and, at the same time, allows for high electrical current to be transmitted through the connection. When two or more wires are inserted into the terminal block, they are secured mechanically and electrically by the contact elements, providing a reliable and secure electrical connection.

Barrier strips are similar to terminal blocks, but feature barrier pieces between the connection points. These barrier pieces are designed to provide a complete electrical and mechanical insulation between two components in the connection. This allows for additional safety and protection, particularly when working with multiple wired connections. The terminal strips are also widely used in automotive systems, with multiple wire connections securely held and isolated by the barrier pieces.
