Appendix
Connection cable cross section, HRC fuse rating
Recommendations to VDE 0100 for fusing and cable cross sections for three phase power
capacitors are listed below.
VDE 0100 recommendations
Cross-section values mentioned below are guideline values valid for operation under normal
conditions and at an ambient temperature of 40 °C. Higher values should be selected if
conditions differ from the norm, such as higher temperatures or harmonic distortion.
Kvar rating at 400 V
Other voltage ratings
The internal wiring of a capacitor bank can be normally done with a lower cross section.
Various parameters such as temperature inside cabinet, quality of cable, maximum cable
isolation temperature, single or multicore cable and length of cable have to be taken into
consideration when selecting the appropriate value.
