SINAMICS G120P Cabinet

Ready-to-connect converter cabinet units in the power ranges from 75 to 560 kW and from 315 to 630 kW.

The SINAMICS G120P Cabinet are available with cabinet widths from 600 mm in various degrees of protection up to IP54, and with two design versions.
  • Version A:
    offers sufficient space for all available options. 
  • Version C:
    space-saving version envisaged for applications where the power supply components are accommodated in a central low-voltage distribution and need to be provided again in the control cabinet.

The SINAMICS G120P Cabinets are available with du/dt-filter compact plus VPL (Voltage Peak Limiter). They limit both the voltage unit du/dt and the peak voltage to the strict limits of the standard IEC 60034-25. This reduces the load on the motor insulation and extends the service life of the motor.
