Derating of cable length

The derating values for the cable length as a function of the ambient temperature T > 40 °C can be found in the following tables:

Inverter

Uline: 3 × 400 V, 3 × 500 V

Calculation of the cable length:

MCX91A-0010-5E3-4-.. – MCX91A-0025-5E3-4-..

Lnew/L = 1 - (T - 40 °C) × 5.33% at fPWM = 4 kHz

Lnew/L = 1 - (T - 40 °C) × 6.7% at fPWM = 8 kHz

 

Inverter

Uline: 3 × 230 V

Cable length

MCX91A-0017-2E3-4-.. – MCX91A-0025-2E3-4-..

Lnew/L = 1 - (T - 40 °C) × 5.33% at fPWM = 4 kHz

Lnew/L = 1 - (T - 40 °C) × 6.7% at fPWM = 8 kHz
