Connection box PN plus for Mobile Panels (PROFINET)

In general, a connection box is a device used to facilitate the connection and distribution of electrical or telecommunications cables. It is typically a junction point where multiple cables come together, allowing for easy access and management of the connections. The "PN" part could potentially refer to a part number or a specific model designation, but without additional details, it is difficult to provide a precise explanation.
