Bürkert fulfils DIN EN 61439
The new series of standards for the construction of switch and control systems, DIN EN 61439, will take effect on 1 November 2014, superseding the previous standard DIN EN 60439 with a transition period. Affected are all switch and control systems for the operation of machines and systems, as well as power distributors for high current applications. The reason for the new legislation is to improve the reliability and safety of such systems. The required documentation for planners will increase significantly as a result of the new standard. In the future, detailed type and item certifications as well as thermal calculations will be required for all switch and control systems.
