ALPHA 400/630/1250 DIN installation kit molded case circuit breaker 1x 3VA10-11/100A/160A 3+4-pole H=450mm, W=250mm vertical installation 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 the planning through to the documentation of the energy distributors and installation distributors. The ALPHA distribution systems are available in a wide range of designs and in many special colors. The doors are available in either glass or steel. ALPHA - the system concept counts.
