Siemens SINAMICS V20 6SL3210-5BE24-0UV0 4 kW 3-Phase VFD

Electrical Ratings

This exact converter is rated 4.00 kW (5.00 HP) under both Siemens Low Overload (LO) and High Overload (HO) classifications. Its input is three-phase 380–480 V AC, with the datasheet stating a permitted line-voltage tolerance of −15% / +10% and mains frequency 47–63 Hz. The inverter provides three-phase motor output, with Siemens listing 400 V IEC and 480 V NEC reference ratings. The rated output current is 8.80 A at the 400 V IEC reference and 8.20 A at the 480 V NEC reference, for both LO and HO modes. Siemens lists 11.3 A rated input current for this model in its operating instructions. These values should be checked against the actual motor nameplate and site supply, rather than treated as a guarantee of compatibility with any 4 kW motor.

Drive Control and Performance

The SINAMICS V20 is a compact variable-speed motor converter used to adjust motor output frequency and operating speed. The exact-part datasheet lists a 0–550 Hz inverter output-frequency range and a 4 kHz nominal pulse frequency. The output-frequency maximum must not be interpreted as a safe operating speed for every connected motor, gearbox, pump, fan or other machine. Siemens documents two duty profiles: Low Overload (LO), at 110% of its corresponding rated output current for 60 seconds, and High Overload (HO), at 150% for 60 seconds; both have a 300-second cycle. The continuous current remains the rated current and must not be confused with these short-duration overload capacities. Control selections and motor commissioning must follow the operating instructions and actual load requirements.

Communication and Configuration

This V20 supports USS and Modbus RTU communications as documented on the manufacturer datasheet. These are communications protocols rather than evidence of an integrated Ethernet connection. Siemens specifies standard onboard digital and analog signal connections; the datasheet lists four digital inputs, one relay and one transistor digital output, two analog inputs and one analog output. The integrated operator controls support local setup and commissioning. Communication cabling, controller mapping, serial parameters and appropriate wiring practices must be established during system design. Do not assume that fieldbus expansion hardware, PLCs, communication adapters or extra software are supplied with the drive.

EMC and Braking Configuration

The precise suffix UV0 identifies the unfiltered version. Siemens states “Unfiltered” in the integrated filter field of the exact-part datasheet, so an integrated C3/Class A filter must not be claimed for this variant. If the installation needs an EMC filter, the system designer must confirm a suitable separately selected solution and appropriate cable installation practices. The same datasheet explicitly says “With integrated braking chopper: No”. Therefore, a built-in braking transistor, regenerative braking package or external braking resistor must not be described as supplied with this product. This differentiates UV0 from newer UV1 ordering variants. The machine’s deceleration and stopping performance require application-specific design and verification.

Physical Installation and Environment

The enclosure protection rating is IP20 / UL open type. Siemens specifies FSB frame size, 140.0 mm width, 160.0 mm height and 164.5 mm depth, with an external cooling fan. The published environmental data include an installation altitude reference of 1,000 m, operation in the −10 to 60 °C range subject to applicable derating instructions, and 95% maximum operating relative humidity. These conditions are not permission to ignore ventilation, contamination, clearances, ambient-temperature derating, safe isolation or enclosure selection. Siemens lists maximum motor cable lengths of 25 m shielded and 50 m unshielded in the exact datasheet; confirm installation conditions and the operating manual before final cable selection.

Typical Applications

For a correctly matched three-phase motor and suitable controls, this 4 kW SINAMICS V20 may be considered for variable-speed pump sets, ventilation fans, compact process conveyors, mixers, packaged machinery and similar general industrial automation duties. These are technically suitable application examples rather than proof that this exact variant is qualified for every installation. System sizing should address continuous current, startup torque, overload profile, speed range, deceleration demands and applicable machine-safety protections. Loads requiring frequent or high-energy braking may need a different braking solution. No energy-savings guarantee or universal motor compatibility is implied.

Exact Variant and Lifecycle

The complete Siemens ordering number is 6SL3210-5BE24-0UV0. It is the original 4 kW, three-phase 380–480 V AC, unfiltered UV0 version. Do not substitute technical details from the integrated-filter CV0 version or from the later UV1 generation. In particular, the UV0 drive does not have an integrated braking chopper. The Siemens manufacturer catalogue should be consulted for current lifecycle information and any designated successor, with procurement and retrofit compatibility checked separately. The older 2022 operating instructions list 8.24 A at 480 V under specified 4 kHz/40 °C conditions, whereas the exact-part datasheet rounds the 480 V rated value to 8.20 A. These are retained with their respective source context instead of silently harmonized.
