Terminal Blocks - Barrier Blocks

A 403503 terminal block is a barrier block designed to be used for the application of electrical component connection, termination, and current distribution. The terminal block provides a secure and reliable connection between various electrical components of the system.

Application Field

A 403503 terminal block can be used in many electronic applications, including industrial, automotive, lighting, networking, telecommunications, audio, video, and other specialized applications. It is particularly suitable for equipment and systems that require a direct and reliable electrical connection in the range of 2.5mm to 35mm.

One of the major applications of the terminal block is in the automotive sector, where it is commonly used for controlling in-vehicle lighting or to provide a secure electrical connection between the car\'s vehicle system and the lighting system. Moreover, it can also be used in the telecommunications industry as a way to interconnect sub-components, such as fan units, power supplies, radio boards, and switches. Furthermore, it can be used in the industrial sector, where it is most commonly used in the control of machine-to-machine and machine-to-employee communication.

Working Principle

A 403503 terminal block is a type of barrier block consisting of two parts: terminals and barriers. The terminals are typically made of copper and provide a secure connection point to the system, while the barriers are created by using either metal shields, insulation, or a combination of both. The barriers serve to separate and protect the electrical connections from each other while also providing additional strength and insulation for the blocks.

When a terminal block is installed, it is connected to the system through the insertion of a plug and a screw. The plug fits into the openings in the terminals, while the screws are used to secure the plug in place. Once installed, the electrical connections can be established by attaching electrical wires or cables to the terminals. When the connection is complete, the current will flow through the terminals and the wires, providing the system with a secure and reliable electrical connection.

In order to ensure a safe and secure connection, the terminals must be insulated from each other. This is done by placing insulation between the terminals. This protects the connections from electrical shock and damage and prevents unintentional connections. Additionally, the insulation also helps to reduce the noise generated by the electrical connection.

In addition, the connectors must be protected from damage due to excessive electrical current. To do this, the terminals must be protected from excessive heat and also from physical impact. This protection is provided by the barriers, which are designed to reduce the risk of electric shock, short-circuiting, and high-currents.

Overall, the A 403503 terminal block is a reliable and secure connector for electrical components, making it an ideal choice for electronic applications. With the proper installation and maintenance, the terminal block can provide reliable and secure connections for many years.
