Terminal Blocks - Barrier Blocks are an essential component of any electrical and communications network system. They provide a secure connection between separate components in a network, allowing multiple connections to be made between devices. The CDM-44 is a unique model of terminal block that stands out among other models in its field. It offers a versatile solution for many applications and boasts a design that emphasizes the speed of connections. In this article, we will discuss the application field and working principle of the CDM-44 in more detail.

The CDM-44 terminal block is designed with a minimum current carrying capacity of 45A. It is designed specifically to provide power connections in railway applications, such as in transit systems, and other public and private transportations. It can be used for both indoor and outdoor applications, and its connection contacts are designed with full isolation for safety reasons. The CDM-44 has a wide range of available accessory options, including screw-down connectors, marking plates, front and rear cable glands, handles, break-off tabs and connection covers.

The working principle of the CDM-44 is quite simple yet extremely effective. It is essentially a barrier terminal block that breaks an electrical connection in a network. It works by having one side of an electrically insulated body with multiple connection points that promote the separation of two independent electrical connections. When the two connections meet, the electrical current is broken and the terminal block is effectively off. This process can be reversed when the current is again restored. The CDM-44 is designed with an insulation width of 10mm, which helps reduce the risk of electrical shock from contact with nearby flexible cables.

In addition to its application in railway technology, the CDM-44 is also commonly used in industrial, commercial and telecommunication networks. It is suitable for use in AC and DC circuits up to 5A, and can be used at voltages of 18 – 24 VDC. It is also resistant to the effects of UV radiation, salt water, dust, and corrosion due to its elastomer sealing ring. The CDM-44 is designed for fast and easy mounting and provides quick and safe connection with its snap-in bridge, ensuring users can make the connection and disconnection quickly and securely.

To summarize, the CDM-44 terminal block is a versatile solution for many applications due to its wide range of available accessories and its resistance to extreme conditions. It is suitable for use in railway, industrial, commercial and telecommunication applications, and its simple working principle of breaking and restoring electrical connections makes it a secure and reliable connection option. It is designed for fast and easy mounting and provides quick and safe connection with its snap-in bridge.
