Design verification according to IEC / EN 61439-1, -2

Wöhner stands for competence in the area of the busbar system technology. Good service for our customers is a matter for us. Therefore Wöhner also offers special support in the application of its systems. With this software, we support you in the preparation of design verification to IEC / EN 61439.
