Working Principle of QC201/J Terminal Block

The QC201/J terminal block is a power transfer device, designed for easing the process of transferring power from one point to another. It carries out the basic functions of connecting, disconnecting and protecting the electric current between two devices electrically connected to the same connection point. The main components of the terminal block are the main body, bridges, and fasteners.

The main body consists of the connecting base, the power conductor, and the terminal lug. The base is insulated and the terminals are connected to the base. The power conductor is in direct contact with the terminal. The bridges are housed within the main body and serve to join the positive and negative poles of the terminal. The fasteners join the positive and negative poles together, ensuring electrical continuity and preventing short-circuits.

The working principle of the terminal block is based on the force created by a spring-loaded screw. When the terminal block is connected to an electrical circuit, the spring-loaded screw exerts a force to compress the conductor, connecting the two poles of the power source together. The spring-loaded screw can also be adjusted by turning it, or the terminals can be unscrewed to break the connection.

The QC201/J terminal block is designed to meet the requirements of virtually any electrical application and is capable of distributing power safely and reliably. Its various features allow for easy installation and maintenance, making it an ideal choice for industrial applications.
