If you need the single-line diagram for your CAD software:
Before you can add devices, you need a container for your work.
If you work with low-voltage distribution or building automation, you’ve probably heard the name Elcom 51. In a world constantly chasing the "next big software update," Hager’s Elcom 51 has remained a quiet legend. hager planungssoftware elcom 51
While Hager has introduced newer web-based tools, Elcom 51 (often simply called "the Hager planning software") continues to be the go-to desktop application for serious switchgear planners and panel builders.
Here is why this software still matters and how it can save you hours of manual work. If you need the single-line diagram for your CAD software:
For procurement teams, this is the killer feature. Once a design is complete, elcom 51 generates a comprehensive BOM including:
Hager has launched Hager Config (the web-based tool) for simpler, faster projects. It is great for small residential distribution boards. Before you can add devices, you need a
However, for complex industrial control panels, large KNX projects, or when you need full CAD export (DXF, DWG), Elcom 51 remains the superior choice. It offers depth that a browser simply cannot provide yet.
If you are unsure which enclosure to use, use the Dimensioning feature.
elcom 51 is a discontinued, legacy software solution developed by Hager Group (formerly Hager Tehalit) for the planning and configuration of electrical installations, specifically focusing on building communication, bus systems (EIB/KNX), and distribution boards. It was primarily used in the late 1990s and early 2000s. The software is no longer supported, updated, or compatible with modern operating systems. Its successor is the Hager Planning Assistant (HPA) or other current Hager configuration tools.
