The end cap D-UK 2,5 from Phoenix Contact, manufacturer's number 3001022, is a component for finishing the enclosure of terminal blocks in industrial electrical installations. It serves mechanical sealing and optical finishing at the end of a terminal block row, creating a clean and closed front. The application is in enclosures and distributions where proper and secure mounting of terminal blocks is required. The cap is specifically designed for the D-UK 2,5 terminal block series, which is rated for conductor cross-sections up to 2.5 mm².

End cap for terminal blocks
The end cap is mounted at the end of a terminal block row to close the open side of the terminal. This prevents dust, moisture, or foreign objects from entering the terminal block row and protects the electrical connections. It also ensures a uniform optical appearance of the enclosure front, which is helpful during maintenance and inspection. The shape of the cap is adapted to the dimensions of the D-UK 2,5 terminal block series to ensure secure and form-stable mounting.

Dimensions and design
The end cap has a depth of 30.7 mm, a width of 1.5 mm, and a height of 42.5 mm. These dimensions exactly match the requirements of the D-UK 2,5 terminal block series, allowing it to fit easily into the designated mounting opening. The narrow width of 1.5 mm enables a compact arrangement without significantly increasing the overall width of the terminal block row. The grey colour of the cap is coordinated with the standard colour scheme of Phoenix Contact terminal blocks to achieve a uniform appearance.

Material and application
The cap is made of a robust, electrically non-conductive plastic suitable for use in industrial environments. It is not designed for electrical conductivity but serves exclusively as a mechanical closure. The application is exclusively in conjunction with the D-UK 2,5 terminal block series, where it does not function as an electrical contact or conductor. Mounting is done by simply snapping the cap into the terminal block row without additional fastening elements.

Compatibility and accessories
The end cap is specifically developed for the D-UK 2,5 terminal block series and fits only this series. It is not compatible with other terminal block series from Phoenix Contact or other manufacturers that have different dimensions or mounting concepts. Use with other terminal block series is not intended and may lead to mounting problems or damage. There are no special accessories that must be combined with this cap.

Mounting and installation
Mounting is done by simply inserting the cap into the last position of the terminal block row. No tools or additional fastening elements are required. The cap automatically snaps into the designated groove and remains fixed by form-fit. Installation is carried out after the complete terminal block row has been mounted to ensure the terminals are correctly positioned. Removal is done by carefully prying out or pulling off.

Advantages in operation
The end cap provides a clean finish to the terminal block row, improving the optical quality of the enclosure front. It protects the terminals from mechanical damage and prevents foreign objects from entering. The simple tool-free mounting reduces installation time and minimizes error sources. The use is particularly beneficial in installations with high requirements for cleanliness and order, such as in the food industry or medical facilities.
