If the load is concentrated at one end of the run, the voltage drop is twice the value indicated in the table.For a power factor of1V/100 m/A0.720.300.9V/100 m/A0.670.280.8V/100 m/A0.610.250.7V/100 m/A0.540.22This table is given for three-phases network. The single phase voltage drop is obtained bydividing the three-phase voltage drop indicated above by 0.866. For lower neutral / neutral voltage phase, we divide the voltage drop above by 1.732.Radiated magnetic fieldRadiated magnetic field strength 1 metre from the trunkingBμT< 2 x 10-3< 2 x 10-3Derating in case of harmonicsOperational current as a function of 3rd harmonic contentTHD y 15 %254015 % < THD y 33 %2032THD > 33 %1628Permissible current as a function of ambient temperatureAmbient temperature°C< 353540455055Cœfficient K1%n/a10.960.930.890.85Design guideCharacteristicsCanalis KBA
