The product is an end cap of the D-ST 2,5 series from Phoenix Contact, specifically designed for final covering of terminal blocks in industrial electrical installations. It serves as a mechanical end closure at the end of a terminal block row, protecting connection points from dust, moisture, and mechanical stress. The grey colour of the cap harmonizes with typical industrial component colour schemes and supports visual order within the enclosure. The dimensions of the cap are matched to the standard size of D-ST 2,5 terminal blocks, ensuring a secure and precise fit.

End cap for terminal blocks of size D-ST 2,5 is used in electrical installations to cover the ends of terminal block rows. It prevents foreign objects from entering the terminal openings and protects contact points from contamination. Its use is particularly beneficial in environments with increased contamination risk or in enclosures with open terminal block rows. The dimensions of 29.1 mm depth, 2.2 mm width, and 48.6 mm height correspond to the standard dimensions for this terminal block series, enabling precise installation without additional adjustments.

Functions and equipment in detail include the mechanical end closure function at the end of a terminal block row. The cap is simply snapped onto the last terminal and locks in place via form-fit. The grey surface is robust and resistant to mechanical stress during operation. This is a purely passive component without any electrical function; it serves exclusively for mechanical shielding and securing of the terminal block row.

Technology explained simply shows that the end cap has no electrical properties and functions purely mechanically. It is not connected electrically, but simply snapped onto the last terminal in the row, thereby sealing the open end. The exact dimensions – 29.1 mm depth, 2.2 mm width, 48.6 mm height – are matched to the D-ST 2,5 size to ensure a secure fit. The grey colour is typical for industrial components and supports visual integration into existing enclosure systems.

Compatibility and accessories refers to use with terminal blocks of size D-ST 2,5. The cap is specifically developed for this terminal block series and fits only these. Use with other sizes is not intended and not supported.

Installation and mounting is done by simply snapping the cap onto the last terminal in the row. No tools are required, as the cap is secured by form-fit. Mounting is performed after installation of the terminal block row to seal the end. The exact dimensions ensure a secure and precise fit, without requiring additional adjustments or tools.

Operational advantages lie in easy handling and effective protection. The cap prevents dust, moisture, or foreign objects from entering the terminal block row, which can extend the service life of the installation and increase operational safety. The grey colour supports visual order within the enclosure. As a passive component, it requires no maintenance or power supply.
