Automated buildings and industrial processes, more stringent requirements regarding energy efficiency, and changed load conditions are currently having a significant impact on electrical power distribution. The underlying systems and components need to be communication-capable, highly flexible, and fail-safe – and it also must be possible to smoothly integrate them in different environments. Combined with increasingly stringent standard requirements, the planning of the electrical energy distribution becomes more complex. At the same time, project cycles are speeding up considerably in switchgear and machine building as well as in electrical installation. Our components ensure a fail-safe power supply and can be seamlessly integrated in comprehensive energy efficiency concepts as well as in building and industrial automation. Professional software and engineering data enable efficient standards-compliant planning and error-free configuration and documentation.
