Hager 1-2-3 Schema (also distributed as 1-2-3 Esquema ) is a specialized electrical planning application developed by the Hager Group . It translates a theoretical bill of materials into a fully documented, compliant subscriber or residential distribution box.
: The software is built around a simplified process: define the project, configure circuits and modular devices (like MCBs and RCCBs), and generate the final schema. hager 123 schema free download exclusive
Generates professional-grade reports that can be directly used for assembly, installation, and client proposals.
Instead of drawing lines manually in generic CAD software, users utilize a guided, database-driven wizard. This step-by-step workflow automatically handles the engineering calculations behind panel planning.

Ensures the panel design does not overheat, complying with IEC 61439 regulations [1].
Check the label on your device. Then search Hager’s website with that exact model + “communication manual.”
