Terminal Blocks - Barrier Blocks 0391000809 Application Field and Working Principle

Barrier blocks generally consist of an insulating-shell encasing one or more conductive barriers (strips, screw-type, etc.) and terminals (single or double level). The varieties differ depending on the application, required performance, lifetime, and quality level. These terminal blocks allow the isolated connection of individual wires and cables, permitting quick and simple wiring in electrical systems.

Applications

Barrier blocks can be used for a variety of applications in industrial, home and marine environments. The most common applications include:

• Control wiring
• Energy metering
• Sensor connections
• Data transmission
• Power supply

In industrial environments, barrier blocks are used to connect electrical and electronic components such as thyristors and transistors. In domestic applications, they are used in circuit breaker panels, TV sets, and audio systems. In marine applications, they are used for grounding and short circuit protection for electric circuits on board ships.

Working Principle

Barrier blocks typically feature screw-type terminals or contact strips. Each terminal point has four connection points – two plus and two minus. One plus and one minus are for signal connections; the other plus and minus are for power connections. This allows each individual wire to be routed within the terminal block through a series of barriers. This enables easy and reliable wiring changes throughout the entire system.

The insulated barrier blocks are made of two halves, each containing a terminal point and barrier strip. In some devices, there may also be additional connection points for extra power supplies. The contact strips are usually made from high-grade aluminum alloy or copper and feature high electrical and copper conductivity, durability and corrosion-resistance.

Barrier blocks are simple and robust and can handle high voltage applications. They are also easy to assemble, maintain and modify. In some cases, they may also be configured to handle multiple power supplies or signals. The high-quality electrical insulation and corrosion-resistant materials make them suitable for long-term, reliable use.

Conclusion

Barrier blocks are essential components in electrical systems and serve a variety of applications in both industrial and domestic settings. They provide robust, reliable wiring connections and are designed to withstand high voltage applications. Their simple design and ease of assembly and maintenance make them an ideal choice for use in both long and short-term applications.
