Alpha 400, wall-mounted cabinet, IP55, protection class 2, H: 1100 mm, W: 300 mm, D: 210 mm, RAL 9016. The Alpha installation distributors are a complete system of wall and floor-mounted distributors for the installation of devices up to 400 A. The system concept is key. The Alpha distribution systems are tested according to IEC 61439 and are based on a common platform structure with extensive designs up to 1250 A. Due to the platform structure and modular design, device-specific installation kits can be integrated into various distributor variants. This facilitates planning and assembly. The configuration is done individually and project-specifically. The Simaris Configuration software supports the planning to documentation of the energy distributors and Alpha installation distributors. Siemens Alpha installation distributors are particularly characterized by electrolytically galvanized and powder-coated enclosures, which ensure greater resistance to environmental influences.
