Siemens 6SL32301YH420UB0 SINAMICS G120X Module
Electrical Ratings Summary
| Parameter | Value |
|---|---|
| Output Current | 108 A |
| Supply Voltage Range | 500–690 V AC |
| Rated Motor Power | 75 kW |
| Motor Type | AC Motor |
| Series | SINAMICS |
| Mounting | Chassis Mount |
Environmental and Compliance
| Parameter | Value |
|---|---|
| Enclosure | IP20 / Box |
| Operating Temperature | 20°C to 45°C |
| Product Status | Active |
| RoHS | ROHS3 Compliant |
The chassis-mount form factor positions the unit for cabinet-level installation alongside contactors and motor feeders. The 20–45°C operating window aligns with ventilated enclosure practice for high-power drives; thermal management design (fan sizing, airflow path) falls to the panel builder.
G120X Family and Suffix Coding
The trailing suffix block (UB0) encodes two orthogonal dimensions within the SINAMICS G120X series: unit type/firmware designation and environmental rating classification. The 6SL32301YH420 prefix covers the 75 kW / 108 A performance class across all voltage tiers. Alternate suffixes in this same family include CB0/CF0/CP0 (C-class ratings) and UB0/UP0/UF0 (U-class ratings), which share the identical electrical and thermal specifications. Part numbers with a 21-series prefix (6SL32301YH421) denote the next higher current class in the same power band.
Comparative Options (6SL32301YH420 Family)
| MPN | Suffix Code | Output Current | Voltage | Power | Similarity |
|---|---|---|---|---|---|
| 6SL32301YH420UB0 | UB0 | 108 A | 500–690 V | 75 kW | primary |
| 6SL32301YH420UP0 | UP0 | 108 A | 500–690 V | 75 kW | 1.0 |
| 6SL32301YH420UF0 | UF0 | 108 A | 500–690 V | 75 kW | 1.0 |
| 6SL32301YH420CB0 | CB0 | 108 A | 500–690 V | 75 kW | 1.0 |
The reader must independently verify that the suffix-rated environmental class matches the target installation environment. The UB0 suffix targets U-class environmental conditions; CB0/CF0/CP0 target C-class conditions. All share the same electrical performance envelope. These are parametric alternatives within the same manufacturer line; none constitutes an OEM-approved interchange for a specific application rating.
Why similar (UP0): Identical electrical spec and chassis-mount package; same family prefix; difference is U-class variant code.
Why similar (CB0): Same 108 A / 75 kW / 500–690 V core rating; chassis mount; same SINAMICS G120X series; variant differs by environmental rating class only.
