Siemens 6SL32302YH300AP0 — SINAMICS G120X 18.5 kW Drive Module
Key trade-offs for panel integration
- Chassis mount vs. enclosure packaging — requires dedicated cabinet space with panel cutout or subpanel mounting; no integral DIN-rail accommodation limits flexibility in dense enclosures.
- IP20 rating — provides basic finger protection but no dust or liquid ingress barrier; installation in contaminated or washdown environments demands supplementary enclosure sealing.
- 32 A output @ 500–690 V — output current rating imposes minimum conductor sizing and branch-circuit protection coordination; mismatched cable gauges increase thermal risk at full load.
- Operating range 20°C–45°C — ambient thermal margin narrows in confined cabinets without active ventilation; adjacent heat-generating components can push junction temperatures beyond rating.
- FSD suffix variant differentiation — trailing code likely denotes firmware variant, approval class, or firmware release; incompatible firmware versions affect parameter sets and communication profile compatibility with higher-level controllers.
Performance comparison — G120X 18.5 kW family
The following table compares the seed unit against alternates sharing identical output current and voltage class. Verify functional equivalence independently before procurement.
| Spec | 6SL32302YH300AP0 | 6SL32302YH300AF0 | 6SL32302YH300AB0 | 6SL32302YH300UP0 |
|---|---|---|---|---|
| Current – Output | 32 A | 32 A | 32 A | 32 A |
| Motor Type | AC Motor | AC Motor | AC Motor | AC Motor |
| Mounting | Chassis | Chassis | Chassis | Chassis |
| Operating Temp | 20°C ~ 45°C | 20°C ~ 45°C | 20°C ~ 45°C | 20°C ~ 45°C |
| Series | SINAMICS | SINAMICS G120X | SINAMICS | SINAMICS |
| Similarity | — | 1.0 | 1.0 | 1.0 |
- 6SL32302YH300AF0 — same voltage/current/power; differs by Series descriptor inclusion ("G120X") and firmware suffix; shares chassis mount and 20–45°C thermal window.
- 6SL32302YH300AB0 — identical primary specs; trailing code likely firmware variant; same Siemens SINAMICS platform.
- 6SL32302YH300UP0 — matches output rating and voltage class; U-prefix suggests variant designation; operating temperature reads 20°C~45°C (same range, no space formatting).
Engineering verification checklist
- Confirm output current (32 A) matches motor nameplate full-load amperes for target 18.5 kW AC motor.
- Verify input voltage range (500–690 V) matches available three-phase supply; confirm grounding configuration.
- Validate chassis mounting dimensions against cabinet or subpanel cutout specifications.
- Check firmware suffix compatibility with existing SINAMICS G120X parameter sets and PLC communication profile.
- Confirm ambient temperature at installation point stays within 20°C–45°C range; add cabinet ventilation if necessary.
- Verify IP20 suitability for installation environment; plan supplementary enclosure if exposure risk exists.
- Confirm branch-circuit protection coordination: cable sizing, overcurrent device rating, and short-circuit withstand for 32 A output.
- Review ROHS3 compliance status against end-market regulatory requirements.
