Supplementary data IEC

The following values have been verified with tests under certain conditions. Please ask Wöhner for this conditions before designing your panel.
A fuse-combination unit acc. to IEC 60947-3 can only be operated at a higher voltage than its rated voltage, if it is used as a fuse-disconnector without breaking capacity, up to its max. rated insulation voltage and labelled as such.
Special operating conditions corresponding to IEC / EN 61439-1 may yield to foulty activations of pilot switches and fuse monitors. The operating conditions have to be considered for the analysis of status signals.
