As of version 2025.a, the CYPELEC Core, CYPELEC REBT, CYPELEC NF and CYPELEC RETIE programs are combined into a single program called CYPELEC.
When starting the CYPELEC program, a selection window appears in which the user must select the option corresponding to the code to be applied in the design of the low-voltage electrical system.
CYPELEC allows users to open jobs from previous versions of CYPELEC Core, CYPELEC REBT, CYPELEC NF and CYPELEC RETIE.
