Siemens 6SL32203YE300UP0 — SINAMICS G120X IP20 AC Drive, 380–480 V, 18.5 kW
Overview
This unit is a chassis-mount variable-frequency drive (VFD) in Siemens' SINAMICS G120X series, rated for 18.5 kW motors on a three-phase supply between 380 V and 480 V. The output stage delivers up to 51.3 A to a connected AC motor. The enclosure is rated IP20, placing it in a cabinet or enclosed panel where personnel contact is controlled.
The catalog entry lists the operating temperature window as 20°C to 45°C ambient around the unit. RoHS 3 compliance is declared; the product lifecycle status is marked Active. Neither the catalog fields nor the JSON include the physical dimensions, weight, heat dissipation, switching frequency, EMC filter rating, braking chopper rating, fieldbus interface options, nor the specific firmware version or functional safety rating. Those must come from the official operating instructions and device-specific datasheet.

Critical fields not present in supplied data — selection must not proceed on these until verified against the official datasheet:
- Input current draw at nominal load
- DC-bus voltage and intermediate circuit rating
- Switching frequency (affects audible noise and motor heating)
- EMC filter class (integrated or external)
- Braking chopper and resistor rating
- Fieldbus / communication module slots (PROFINET, EtherNet/IP, USS, Modbus RTU)
- Overload cycling capability and duty-cycle rating (heavy-duty vs normal-duty current)
- Dimensions, weight, cooling method (force-air, external fan kit)
- Degree of protection beyond IP20 for the full enclosure assembly
- Safety function rating (STO / SS1 if applicable)
Integration Notes
The chassis-mount form factor implies direct attachment to a metal backplane or stiff panel inside a protected enclosure. No DIN-rail clip is listed; confirm mounting bracket availability for the specific frame size before ordering.
The 20°C–45 °C ambient window is relatively narrow for industrial environments with heat-generating equipment nearby. Thermal management—forced-air circulation, enclosure sizing, clearance around heat sinks—must be designed per the datasheet's thermal derating charts, not estimated from these catalog fields.
The IP20 rating classifies the drive itself; the overall cabinet IP rating depends on the enclosure design and any field-installed covers or cable glands. Verify the mechanical interface requirements for power and motor cables (terminal sizes, torque values, cable cross-section range).
The G120X series supports multiple control interfaces and plug-in function modules. The catalog entry does not specify which is installed; the MPN suffix encodes firmware and hardware variants. For a new design or replacement, confirm the exact suffix matches the installed hardware and the target PLC network.
Ordering-Code / Family Context
Siemens VFD part numbers use a structured code: the prefix 6SL3 identifies the drive hardware family, and the subsequent digits encode power rating, voltage class, firmware version, and firmware type (e.g., UP0 versus UF0). Within the G120X 18.5 kW / 380–480 V group, the MPN suffix variation (P0 / F0 / B0) and the three-digit build code (300 vs 301) differentiate firmware parameters, integrated options, or firmware version. Verify the suffix against the existing drive nameplate or the engineering bill of materials; using the wrong firmware variant may cause parameter incompatibility or missing functions in the commissioning tool.
Similar Catalog Parts
The catalog returned eight alternates, all with similarity 1.0 and identical key spec values (same output current, voltage range, power rating, mounting, temperature window, and ROHS status). The differences are confined to MPN suffix and firmware version.
| Parameter | 6SL32203YE300UP0 | 6SL32203YE300UF0 | 6SL32203YE300AP0 |

| Similarity | — | 1.0 | 1.0 |
Only the top two alternates by MPN prefix relevance are shown. Remaining listed alternates: 6SL32203YE300UB0, 6SL32203YE300AF0, 6SL32203YE300AB0, 6SL32203YE301UP0, 6SL32203YE301UF0, 6SL32203YE301UB0.
Why they are similar: Each alternate shares the same G120X power stage (18.5 kW, 380–480 V, 51.3 A output), the same chassis-mount form factor, and the same ambient temperature window. The suffix variation (UP0/UF0/AP0) and the build code (300 vs 301) indicate a different firmware parameter set or installed module variant, not a different power hardware stage. The shared spec keys do not reveal the firmware type; check the specific ordering-code breakdown in the Siemens catalog or the installed unit's nameplate.
Verification Before Selection
Before committing to any of the listed MPNs:
- Confirm the firmware variant suffix matches the target application (control mode, safety function, communication interface).
- Verify the overload rating and duty cycle (normal duty vs heavy duty current values) against the motor nameplate and load profile.
- Obtain the dimensional drawing for chassis cutout, depth, and mounting hole layout.
- Identify any required accessory (fan kit, EMC filter, braking resistor, line reactor) not included in the base unit price.
FAQ
Does 6SL32203YE300UP0 include an integrated EMC filter?
The supplied catalog fields do not specify an EMC filter class. The G120X series offers multiple filter options (category C1/C2/C3) as separate modules or built-in variants. Verify against the official operating instructions.
Can 6SL32203YE300UP0 be used as a direct replacement for 6SL32203YE300UF0?
Both units share identical power-stage ratings (18.5 kW, 51.3 A, 380–480 V). Substitution may be viable if the firmware variant suffix matches the application. If the installed UF0 unit has a specific parameter set or safety function, load that configuration before commissioning the UP0 unit, or the drive may fault on first start.
What is the minimum enclosure IP rating for IP20-rated drives in an industrial cabinet?
The drive itself is IP20; the cabinet enclosure must be designed to protect the drive from dust and foreign objects. Typical panel builders specify IP54 or IP65 cabinets for wash-down or dusty environments, but the drive's internal temperature and cooling path must be validated against the datasheet thermal data.
