This software for low-voltage distribution systems and meter cabinets (ALPHA distribution boards for electrical installations, ALHA 400-ZS meter cabinets, 8HP insulated distribution systems, ALPHA BOX, BETA built-in devices, GAMMA building management systems) enables planners and electricians to produce configurations of distribution boards and meter cabinets easily and quickly. Easy functions that are intuitive to operate lead all the way from configuration to installation. Configuration errors are almost eliminated by collision tests and configuration rules which are defined in the program. Tenders can be prepared easily thanks to a clear output selection structure for generating printouts or data output of parts lists, the layout diagram, set-up and electrical structure.
