The International Products and Services Classification Standard

Zuken is a supporting member of the international eCl@ss standard, the classification system for the description of products and services for achieving standardized product information. Zuken’s objective of membership is to influence the development of standards to support customers of electrical CAD, including our electrical CAD software suite, E³.series.

For users of E³.series, having complete component data from the onset of a design project provides many benefits. E³.series is an intelligent component-oriented engineering design solution for wiring and cable design (rather than a non-intelligent symbol-oriented drawing solution). This allows engineers to make full use of the component information when making engineering decisions.

The component data currently contained within the E³.series component library from members of Zuken's Component Manufacturers Alliance Program (CMAP) are compliant with the eCl@ss standard. Zuken’s CMAP is open to all component suppliers.
