Terminal Blocks - Barrier Blocks

A Barrier Block is a type of electrical device that allowwires and cables to be connected to one another. They are essential for effectively and safely connecting electrical devices. One type of barrier block, called the CFT-23, is typically used in applications where two junctions are required for electrical power and grounding. This article explains the application field and working principle of the CFT-23 barrier block.

Application Field

The CFT-23 barrier block is mainly used in two places. The first is in electrical control cabinets, where it is used to connect electrical lines, power supply cables, and field instruments. The second is in the automation industry, where it is used to connect parts of automated production machines. The CFT-23 is especially suitable for high density connections in these places.

Working Principle

The CFT-23 barrier block has two tie bars that are connected to the opposite side. The connection is completed by inserting a cable into the front of the tie bar and tightening the two screws on either side of the tie bar. This allows the wire to be firmly connected to the barrier block. The ground connection is then made by inserting a grounding wire into the rear of the tie bar and tightening the two screws. This completes the connection and places the electrical load into an isolated circuit. Then, when a high-voltage power source is applied to the block, the current flows through the isolation gap between the ties, thus safely protecting the electrical device.

Conclusion

The CFT-23 barrier block is a useful electrical device that can be used to safely and effectively connect electrical lines and power supply cables. It consists two tie bars that are secured in place with screws, and the ground connection is then made by inserting a grounding wire in the rear. Once the connections are complete, a high-voltage power source can be applied to the block, allowing thecurrent to flow through the gap between the ties without damaging the equipment. The CFT-23 is particularly well suited for applications such as electrical control cabinets and the automation industry.
