Terminal Blocks - Barrier Blocks

0387306712 application field and working principle is a type of terminal block that connects adjacent electrical circuits to conduct a safe electric current for power connection and signal transmission. The terminal blocks consist of two parts, a grounding block and a barrier block.

Grounding Block

The grounding block is a fuse holder designed to serve as a protective layer for the connected circuit, providing a safe and reliable connection. It is connected to the ground, and its insulation is ensured by epoxy resin, preventing interference from other electrical components and reducing the possibility of short circuits. In addition, it provides a certain degree of tensile strength, to help maintain stable electrical connections.

Barrier Block

The barrier block consists of two parallel conductors, and a conductive barrier between them. Its main function is to establish a disconnection between the two conductors. It also prevents voltage drops, maintains the integrity of the circuit, and prevents overcurrent. The barrier block also amplifies and optimizes the range of application of a single current, allowing for more efficient use of the electrical circuit.

Application Field

Terminal blocks – barrier blocks are widely used in electrical systems for connecting, disconnecting, protecting, and controlling circuits, as well as signal transmission. Typical electrical applications include control circuits, lighting, and motor controls. They are commonly used in industrial, commercial, and residential electrical systems, and are especially useful in hazardous locations.

Working Principle

The barrier block essentially works in the same way as a fuse, however, instead of interrupting the current flow when it exceeds an unsafe level, the conductive barrier simply blocks it from entering the circuit. When the current passes over the barrier block, an arc is produced as a result of the contact between the conductors, causing the current to be weakened. Thus, it prevents the current from entering the connected circuit, providing an effective protective layer against overcurrent or short circuits.

Conclusion

Terminal blocks – barrier blocks are an essential safety device in electrical systems. They provide protection against overcurrent and short circuits, and provide a reliable and secure level of connection. They are used in a wide variety of applications, and are especially useful in hazardous locations, where contact with high voltage items is a possibility. With their reliable and efficient performance, terminal blocks – barrier blocks are an indispensable component of electrical systems.
