ALPHA 400/630/1250 DIN installation kit fuse switch disconnector 4x 3NP4070 Installation on support plate including matching cover H=300mm, W=500mm The ALPHA installation distributors - a complete system of wall and floor-standing distributors for the installation of devices up to 1250 A. 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 everything from planning to 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.
