Siemens 6SL32301YC221UB0 Variable Frequency Drive

Overview

The 6SL32301YC221UB0 is a chassis-mount variable frequency drive (VFD) from Siemens' SINAMICS G120X series, rated for 5.5 kW AC motors on a 200–240 V supply. The data source provides limited electrical parameters; critical ratings including input current, switching frequency, braking transistor presence, communication interfaces, and short-circuit current rating are not listed and must be confirmed against the official Siemens datasheet before any selection or panel design work.

Key Parameters (from supplied catalog fields)

The input voltage window (200–240 V) and power rating (5.5 kW) appear in the catalog title but not as structured spec keys. Thermal management, EMC filter class, DC braking capability, and overload duty cycle class are not populated in the supplied data.

Ordering-Code / Family Context (verify on datasheet)

The MPN prefix 6SL3230 identifies this as a SINAMICS power module. The segment 1YC22 encodes the 5.5 kW / 200–240 V rating; the trailing 1UB0 suffix conventionally designates the frame size (FSC) and firmware/variant code for Siemens G120X drives. The exact meaning of each character position is Siemens-internal; consult the G120X ordering guide to decode variant suffixes.

Integration / Installation Notes

The following physical and electrical integration details are not specified in the supplied fields and must be obtained from the datasheet:

• Required enclosure ventilation / derating above 45 °C ambient
• Fieldbus communication options (Profinet, Modbus RTU/TCP, CAN, or analog/digital I/O only)
• DC bus braking resistor connection and current rating
• Short-circuit current rating (SCCR) for branch coordination
• Wire gauge / terminal torque specifications for load and supply connections
• EMC compliance class (Class B/C2/C3) and whether an internal EMC filter is present
• Bypass / motor starter integration provisions

This is a chassis-mount unit intended for installation inside a cabinet or enclosure; the IP20 rating confirms it is not suitable for field mounting without additional protection.

Selection / Substitution Guidance

All listed alternates share the same 29.7 A output rating, IP20 chassis-mount form factor, and G120X series designation:

The similarity scores of 1.0 reflect catalog-level metadata matching (brand, category, series, primary electrical parameters) and do not indicate interchangeability without verifying the suffix-specific variant differences. Substituting even within the same power rating requires confirmation that the firmware variant, certification (UL, CE), and optional interface cards are compatible with the target application.

Verification Required Before Use

• Input current draw and branch-circuit protective device sizing
• Overload and short-circuit current ratings for NEC/UL coordination
• Minimum enclosure sizing and ambient temperature derating curve
• Communication option modules if network integration is required
• Applicable standards compliance (UL, CE, UKCA) for the installation region

FAQ

What motor shaft load can 6SL32301YC221UB0 drive? The catalog lists AC Motor type and 5.5 kW rating. Motor nameplate current, poles, and service factor must be verified against the drive's current derating table to confirm compatibility.

Does 6SL32301YC221UB0 include an integral EMC filter? The data source does not specify EMC filter presence. This must be confirmed on the Siemens datasheet, as it affects conducted emissions compliance and may influence installation routing.

Can a G120X drive with suffix UP0 replace the UB0 variant? Both are listed with identical output current and mounting. The suffix difference may indicate firmware variant or regional certification; substitution must be validated with Siemens technical documentation.
