A-TB500-OQ20CH Application Field and Working Principle

Terminal Blocks - Headers, Plugs and Sockets are an important part of the equipment power system and signal system. The terminal blocks-headers, plugs and sockets plays an important role in connecting the system lines, power system equipment and signal system components. A-TB550-OQ20CH is a commonly used terminal block that combines headers, plugs and sockets.

Application Field

A-TB500-OQ20CH is mainly used in the power system and signal system fields. In the power system field, this type of terminal blocks are especially suitable for transmission lines up to 500 Vac with power isolation. Commonly used in industrial, commercial and residential facilities, these terminal blocks can withstand up to 80 Vac, will not burn out, spark or draw any current. In the signal system field, this type of terminal blocks are suitable for connecting varieties of apparatus or parts in the signal system, thus forming a signal transmission network.

Working Principle

The A-TB550-OQ20CH terminal block is composed of a base, a connection terminal and a fixing plate, where the combination of these three parts provides a firm and durable connection. During operation, the wires are inserted into the connection terminal. When the fix plate is pressed down, the connection is complete. This type of terminal block allows for a quick and secure connection to make the power and signal transmission much easier.In addition to providing a secure connection, the A-TB500-OQ20CH terminal block also provides electrical insulation, and thus limits the potential power fault risks. This is done by minimising the electrical contact diameter - once contact is made the electrical current is reduced and the potential of an electrical fault is minimised.

Conclusion

A-TB500-OQ20CH terminal blocks are an essential part of any power and signal system. Their combination of headers, plugs and sockets provides a secure connection and efficient electrical insulation, making them suitable for any signal or power system.
