Terminal Blocks - Headers, Plugs and Sockets: The ELFH0721G is a DIN rail terminal block, a type of electrical connector or interface often used in automation and control applications. It is characterized by its versatility and multipurpose use, as it facilitates the connection and disconnection of wires. The ELFH0721G is 9.2 mm in width and 21 mm in height and is usually found in 19 mm or 35 mm DIN mounting rails.

Applications for DIN rail terminal blocks such as the ELFH0721G include cabinets housing electronic devices and other control systems, junction boxes, and lighting systems. Generally, the DIN rail terminal block is used as an interface for connecting wires in the aforementioned applications. For example, one could mount the ELFH0721G on a DIN rail in a cabinet and run the needed wires from the device to the connector. The ELFH0721G facilitates the connection between wires and other components and devices within a system and makes patching and rewiring simple and efficient.

The ELFH0721G also has a rated operating voltage of 300/500 V and a rated current of 16A. Additionally, it has a removable jumper link to facilitate the expansion of systems. It is a one-piece construction which has solid and stranded wires which pass through it for easy connection, comes with color-coded screws for proper identification in a system, and possesses a polyamide housing for insulation and protection. The jumper link connection, insulation, color-coded screws, and DIN rail mounting support make the ELFH0721G the ideal choice for many automation and control applications.

The working principle of the ELFH0721G, along with other types of DIN rail terminal blocks, is that it provides a secure connection between wires for different systems and equipment. It is a one-piece electrical connector which has a clip or screw that secures it to the rail mount, and solid and stranded wires pass through the connector. On one end of the ELFH0721G is an open clip, into which wires can be inserted. On the other end is a screw that securely fastens the clip to the rail mount, thereby completing the circuit and making a secure connection between the wires. This ensures that wires don’t become loose and that the system functions properly.

In summary, the ELFH0721G terminal block is a versatile, multipurpose electrical connector that can be used for a variety of applications. It has a durable polyamide housing for insulation and protection and is fastened securely to the rail mount with a clip and screw. The rated operating voltage and current are suitable for most systems, and its jumper link connection capability make it ideal for automation and control applications. The one-piece construction, color-coded screws, and solid and stranded wires ensure a secure connection between wires and other components in a system, and provide an example of the working principle of DIN rail terminal blocks.
