Terminal Blocks - Barrier Blocks (Part Number 0387320005) are electrical interconnection devices that provide an economical and easy way to connect a power supply to multiple circuits or components. The barrier blocks are generally used in industrial and commercial applications, such as power supplies, batteries, audio systems, and monitoring systems. They are also widely used in manufacturing lines, research laboratories, and electrical systems for medical and military purposes.

Basic Function

The main purpose of Barrier Blocks is to provide a safe and reliable connection between electricity sources and circuits or components. In other words, the terminal blocks are designed to provide a simple connection between a power supply and an electrical device separated in different areas, or even different rooms. The advantage of using barrier blocks is that it seals the connection and provides protection against accidental contact with live conductors. It also prevents the spread of electric arcs that can cause a spark and burn the insulation around the current path and create hazardous electric shock.

Materials Used and Types

Barrier blocks are made of aluminium, zinc, stainless steel, brass and other conductive materials. Depending on the application, they can be mounted in different positions such as vertical, horizontal, or diagonal. Barrier blocks also come in different sizes, designs, and shapes. The most common type of these blocks is the barrier type, which has different compartments on each side. Other varieties include bridging blocks, strip blocks, continuous pin blocks, and pluggable blocks.

Working Principle

A barrier block usually consists of a terminal block and a cover. The terminal block has two sides; one side is designed to connect the incoming power supply, while the other side is used to connect the other components of the circuit. The connector pins in the terminal block have a recessed section in the middle so that the cover fits snugly over them. When the cover is closed, the pins are blocked off, effectively creating a barrier that will prevent the power from flowing between circuits or components unnecessarily.

The terminal blocks also have a predetermined number of pins for electrical connection. The metal casing surrounding the pins is usually insulated, and it will serve as a barrier between the pins and any other conductive parts. Additionally, the terminal blocks have different colors for each type of connection and the pins are connected with either screws or bolts.

Advantages

Barrier blocks have a number of advantages over other electrical interconnect devices. They are easy to install and highly reliable. Once installed, the barrier blocks provide the connection between the power supply and other components in a secure manner. The blocks can also be easily modified or replaced since they are designed in a modular fashion. Additionally, since they offer a secure connection, they can be used in hazardous or high-voltage applications.

Barrier blocks also provide the greatest flexibility of connection. They provide both a direct and indirect connection without any damage to components. They also provide improved resistance to high and low temperatures and offer maximum protection against electrical shock and fire. Furthermore, the blocks require minimum maintenance and the materials used are corrosion-resistant. The blocks are flame retardant and offer the highest level of safety even in dangerous applications.

Conclusion

Barrier blocks are an essential component in modern day electrical systems. By providing a secure connection between electricity sources and devices, they prevent the spread of electric arcs and hazardous contact with live conductors. The blocks are reliable, easy to install and require minimal maintenance. Additionally, they offer maximum protection against electrical shock and fire. They are especially suitable for industrial and commercial applications, as well as for hazardous or high-voltage applications.
