ALPHA 400 DIN, longitudinal stays for mounting of assembly kits, H=1400, 1 set=2 stays The ALPHA distribution board is a complete system consisting of wall-mounted and floor-mounted distribution boards for installing devices up to 1250 A. ALPHA – the system idea counts. The ALPHA distribution systems are tested in accordance with IEC 61439 and are based on a common platform structure with comprehensive designs up to 1250 A. Due to the platform structure and the modular layout, the device-specific assembly kits can be integrated in various distributor variants. This facilitates planning and installation. The equipping is done individually and project-specifically. The configuration software SIMARIS configuration provides support from planning to the documentation of the power distribution boards and the ALPHA distribution boards.
