A20420404R48

A20420404R48 is a type of terminal block belonging to the barrier blocks family. It’s a screw terminal block with 4 poles, quick connect system, 20A current rating, UL, CSA and VDE certification. It has been primarily designed for use in thermoelectric, motor control, power and electronic circuit applications. The terminal block is made of corrosion-resistant high-performance nickel-plated brass, which ensures a reliable interconnection for power applications requiring specific ratings and is suitable for industrial environments. The block provides secure connection with transmission security up to 400V. The 4-pole design offers a consistent power connection, reducing assembly time and error.The basic working principle of the terminal block is the same as that of a standard barrier block. When connecting a wire or other electrical conductor to a terminal block or any other electrical device, an internal spring inside the terminal block tightly grips the wire and creates an electrical connection. This ensures that the electrical current flowing through the block is transferred from one device to the other in a timely and secure manner. Furthermore, the spring also serves to ensure that the connection remains secure, and does not loosen or disconnect when the electrical current is passing through it. So no matter how many times the electrical current passes through the block, the connection will remain secure and intact. Another added feature of the A20420404R48 terminal block is its built-in safety protection. This safety feature is provided in the form of a lever that automatically locks into place if the current through the block is higher than the intended value. In addition, the built-in protection ensures that the block is de-energized when the circuit is broken or when the wire is disconnected, thus reducing the chances of electric shock. In conclusion, the A20420404R48 terminal block is a great choice for a variety of applications ranging from thermoelectric and motor control to power and electronic circuit applications. It features a secure and reliable connection with transmission security up to 400V, and its built-in safety protection makes it a safe choice for any electrical application.
