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. | |
| Degree of protection IP30 at front, degree of protection near terminal depends on installation |
