Why these parts appear similar
The MPN suffix variants (CB0, CF0, CP0, AB0) share the same Siemens 6SL32 family prefix and identical ratings for output current, motor type, voltage class, power class, and mounting. The differing suffix characters encode variant-specific options (such as the EMI class indicated by the C3 or C2 designation in the title); the on-record specifications do not distinguish between them on current, voltage, wattage, or thermal limits.

Engineering context
The 6SL32303YE540CB0 belongs to the Siemens SINAMICS G120X series, identified by the 6SL prefix. The MPN suffix block encodes variant-specific options including the EMI class (C3 designation present in the catalog title). The G120X platform is a modular drive system intended for integration into customer-supplied enclosures or electrical rooms; chassis-mount packaging places thermal management responsibility on the installing party within the specified operating band of 20°C to 45°C ambient.
This part operates at 380–480 V three-phase and drives AC motors up to 250 kW. No in-catalog entry specifies overload duration, braking transistor rating, fieldbus communication options, or electromagnetic compatibility test levels beyond the C3 class designation — those details require Siemens G120X documentation outside this catalog record.
FAQ
What motor rating does the 6SL32303YE540CB0 support? The catalog entry lists a 250 kW AC motor rating and 644 A output current. The input voltage window is 380–480 V three-phase.
What enclosure rating applies? The title specifies IP20. This is a chassis-mount device with no integral enclosure; the IP20 rating applies to the module itself when installed in a suitable enclosure system.
Does the 6SL32303YE540CB0 include a built-in filter? The title includes the "FSG" designation, indicating a filter variant. The exact filter class (first letter F) aligns with the C3 EMI class shown in the product title.
