Alpha 400, quick assembly kit H=1200, W=500, 2 terminal blocks, 6 rows of distribution. The Alpha installation distributors are a complete system of wall and floor distributors for the installation of devices up to 1250 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 simplifies planning and assembly. The configuration is done individually and project-specifically. The Simaris Configuration software supports the planning and documentation of the Alpha energy distributors and installation distributors. The Siemens Alpha installation distributors are particularly characterized by: 1. For easy and quick assembly, the installation kits consist of device-specific mounting plates and field covers. 2. Quick assembly.
