Alpha 400, wall-mounted cabinet, flat pack, IP43, protection class 2, H: 1250 mm, W: 550 mm, D: 210 mm, RAL 9016. The Alpha installation distribution boards 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 configurations up to 1250 A. Due to the platform structure and modular design, device-specific installation kits can be integrated into various distribution variants. This facilitates planning and assembly. The equipment is customized and project-specific. The configuration software Simaris Configuration supports the planning and documentation of the Alpha energy and installation distribution boards. Siemens Alpha installation distribution boards are particularly characterized by their electrolytically galvanized and powder-coated enclosures, which ensure greater resistance to environmental influences.
