Terminal blocks, also known as “connectors” or “terminals”, are used to terminate electrical connections and form electrical bridges from one circuit to another. They are available in various shapes and sizes from small connectors for DIY projects to large terminal blocks that can be used in industrial settings. In recent years, din rail and channel terminal blocks have become increasingly popular for low voltage applications due to their robust build quality and easy installation. In this article, we will discuss the common application field of din rail and channel terminal blocks, as well as their working principle.

Application Field

Din rail and channel terminal blocks are mainly used in low voltage applications to form electrical bridges between electrical components. They are often used in communication or control systems, household wiring systems, automation equipment, and many other applications. Their low profile design also makes them suitable for applications in limited space. Furthermore, they can be used in environments with high temperatures because they are designed to withstand high temperatures of up to 190°C.

Working Principle

The working principle of din rail and channel terminal blocks is relatively simple. The terminal block consists of two main components - a terminal head and a contact. The terminal head is designed to fit into a pre-drilled hole in a panel or wall and is connected to the power source. The contact component is then connected to the electrical device. When the two components are connected, an electrical connection is created. This connection is then used to transfer electricity from the power source to the device.

When connecting the terminal block, the contact component must be placed in the correct orientation. This is done by using the marking on the contact component – different contacts will have different markings. The contact closest to the terminal head should be marked “+” for positive and “-” for negative. Once the contact is in the correct orientation, the terminal head can be tightened to create a strong connection.

Conclusion

Din rail and channel terminal blocks are widely used in low voltage applications. They are easy to install and allow for secure and reliable electrical connections. Furthermore, they are robust and durable, making them ideal for applications in harsh environments. Understanding their application field and working principle is essential for successful installation and safe operation.
