▼Chapter 7Cable diameters & fuse sizingfor power factor correctionWe provide general non-binding information about common practices in this table. Connection diameters and the fuse rating aredependent upon the nominal power of the PFC system, the national regulations, the cable material used and the environmentalconditions. The recommendation for fuse amperage is only for short-circuit protection, HRC fuses are not suitable to protectPFC capacitors against overloading. The system manufacturer or the planning office is responsible for calculating and selectingcable diameters and fuses for each individual case.PFC cable diameters, fuses (for 400V/50Hz) networksPower inkvarNominal current inACable diameterNYY-J mm 2HRC fuseA5 7 4 x 2,5 167,5 10 4 x 4 2010 14 4 x 4 2512,5 18 4 x 6 3515 22 4 x 6 3517,5 25 4 x 10 5020 29 4 x 10 5025 36 4 x 16 6330 43 4 x 16 8037,5 54 4 x 25 10050 72 3 x 35/16 12555 - 65 79 - 94 3 x 35/16 16070 - 85 101 - 123 3 x 70/35 20086 - 100 124 - 145 3 x 95/50 250101 - 125 146 - 181 3 x 120/70 250126 - 160 182 - 231 2’’ 3 x 70/35 315161 - 180 233 - 260 2’’ 3 x 95/50 400181 - 200 261 - 289 2’’ 3 x 120/70 400201 - 250 290 - 361 2’’ 3 x 150/70 500251 - 300 362 - 434 2’’ 3 x 185/95 630Connection diameters are only valid for the given capacitor power levels▼PFC systems with a power level of more than 300 kvar have 2 separate bus bar systems and require 2 separate feeders. The tableapplies to conventional or de-tuned PFC systems. The actual valid regulations (e.g. DIN VDE 0298) must always be observed.Important note: the bus bar separation must be allocated before extending any existing systems.207
