The LPI connection strips are designed for connecting power, neutral, or protective conductors. They include two versions: LPI-6, which allows the connection of six cables, and LPI-14, which allows the connection of fourteen cables.

Each strip consists of an insulating body and a brass terminal strip. The base of the body is available in gray and yellow colors, while the cover is available in blue, green, and black. The base design allows mounting on a TS35 rail, 12x2 rail, or directly on a surface with screws.

The cover features slots for DK-type markers and digital labeling of individual terminal circuits. The LPI connection strips can also be mounted on Ws-type supports to form an insulating block of 2 to 4 strips called BLPI. The Ws-type supports allow mounting on a surface or TS35 rail and are equipped with slots for markers.

The BLPI block can consist of LPI strips with six or fourteen terminals. A special yellow-green version is also available exclusively for use in protective conductor circuits.
