Terminal Blocks - Barrier Blocks

431613-09-0, or Barrier Blocks, are devices that prevent two electrical circuits from cross-talking or interconnecting. They are used primarily in areas where different voltages or signals needs to be isolated and also in power control, motor control and other industrial applications. A Barrier Block allows the simple and cost-effective connection of electrical or other components in a manner that completely prevents the passage of an electrical signal between the two separate circuits.

Application Field

Barrier Blocks are commonly used in applications where electrical isolation is required between two or more circuits. Areas such as motor control, lighting, automotive, instrumentation and control, and power control all use barrier blocks. In these applications, signals need to be isolated between two or more circuits, while still providing easy connections. Barrier Blocks offer low cost, easy maintenance and efficient ways to create electrical isolation.

Working Principle

The primary way that Barrier Blocks work is to create an electrical barrier between the two circuits. This barrier is created by the use of insulating materials and basic design principles. The first step is to ensure that the area between the two circuits is warm and dry. This is done by using a dielectric material, such as a type of enclosed barrier housing, to prevent the passage of any voltage from one circuit to another. The second step is to use barriers and dividers to physically separate the two circuits.

To further ensure that there is no electrical connection between the two circuits, each area is isolated by using a set of screw terminals. These screw terminals have a hole in the center which houses a small pin. The screw terminals provide a physical separation of the two circuits, as well as forming a potential barrier between the two circuits. This ensures that any electrical signal originating in one circuit will be blocked from entering the other circuit.

Finally, Barrier Blocks also use low-voltage surge protection and/or low-power-voltage clamping devices to further protect the circuits from cross talk. These devices ensure that even if a high-voltage surge is present, the surge will be clamped or “short-circuited”, preventing the passage of any high-voltage to a sensitive area.

Conclusion

Barrier Blocks are important components for any electrical system. By providing a complete form of electrically isolated connection, Barrier Blocks allow for a clean and efficient power control and signal separation between two or more circuits. As a result, these components are an extremely important part of any industrial setting, where reliable and efficient power control is a necessity.
