Terminal Blocks - Accessories - Wire Ferrules are commonly used in 77/20VZ applications. They provide a secure connection to wires and provide reliable electrical performance while protecting the wire insulation from the high current of the circuit.

Applications

The 77/20VZ is typically used in conjunction with terminal blocks for industrial applications. It is used for sensitive applications, such as control systems, communications systems, and sensitive electronic devices. It is also used in the construction industry, for temporary connections. In addition, it can be used in non-standard industrial systems such as LED lighting, telecommunications, or intranet digital systems.

Working principle

The 77/20VZ has two parts: the ferrule and the terminal block. The ferrule is a hollow metal tube that the wire is inserted into. The end of the ferrule is crimped into the terminal block. The crimp connection provides a secure, reliable electrical connection between the wire and the terminal block. The terminal block holds the wire in place and prevents it from vibrating or being displaced when connected to the circuit.

Advantages

The primary advantage of the 77/20VZ is its ability to provide a very secure, reliable connection between the wire and the terminal block. It also prevents any accidental disconnection of the wire, which could cause damage to the associated circuit. Additionally, it prevents any physical stress, vibrations, or displacement of the wire when it is connected. Furthermore, it is able to withstand high current, making it suitable for use in high current applications.

Disadvantages

The primary disadvantage of the 77/20VZ is its relative complexity. It requires more expertise and time to connect it compared to other terminal blocks. Additionally, it can be difficult to disassemble or replace due to the crimp connection. Also, if the connection is not done properly, there is a risk of short circuit and other electrical hazards.

Conclusion

The 77/20VZ is a reliable and secure electrical connection for industrial applications. It is suitable for use in high current applications and provides a secure connection between the wire and the terminal block. However, due to its complexity, it can be difficult to disassemble or replace. That said, with proper installation, it can provide reliable, long-term performance in industrial applications.
