Connectable Conductor Cross-Sections For Spring-Loaded Terminals; Connectable Conductor Cross-Sections For Screw Terminals - Siemens SINAMICS S120 Combi User Manual

Example for dimensioning a power cable
Boundary conditions:
Module: S120 Combi 4 axes Power Module with 20 kW infeed
Rated input current at 400 V
Ambient temperature: 45°C
Installation type: B2
Calculation/dimensioning:
With installation type B2 and a rated input current of 34 A
current-carrying capacity, a cable cross-section of 10 mm
With a derating factor of 0.91 for 45°C ambient temperature, the current-carrying capacity of
the selected power cable decreases to 36.4 A.
Result:
Under the given boundary conditions, a power cable with a cross-section of 10 mm
used.
