The ALPHA distribution systems are tested according to IEC 61439. Due to the modular design and a common platform structure, the device-specific installation kits can be integrated into various distributor variants. This makes planning and assembly easier. The equipment is installed individually and project-specifically. The SIMARIS configuration software supports the planning through to the documentation of the energy distributors and installation distributors. The ALPHA distribution systems are available in extensive designs and in many special colors. The doors are available in either glass or steel. ALPHA - the system concept counts.
