Siemens SINAMICS V20 15 kW 3-Phase VFD 6SL3210-5BE31-5UV0

Electrical Ratings

The 6SL3210-5BE31-5UV0 is rated for a 15 kW / 20 HP three-phase motor application under the Siemens-defined voltage and loading conditions. The input is three-phase 380–480 V AC, with a permitted supply tolerance of −15% to +10% and a line frequency of 47–63 Hz. The inverter supplies a three-phase motor output; Siemens lists 400 V IEC and 480 V NEC rating bases. The continuous output current is 31.00 A in both Low Overload and High Overload modes. The manufacturer operating instructions separately give a rated input current of 38.1 A. Output frequency is adjustable over 0–550 Hz; this limit is not a blanket permission to operate any connected motor or driven mechanism at maximum speed.

Control Modes and Performance

The SINAMICS V20 is intended for straightforward adjustable-speed control of three-phase asynchronous motors. Siemens provides V/f-based operation and commissioning parameters for practical industrial drives. Motor nameplate data, acceleration and deceleration ramps, direction, and operating limits should be configured for the actual installation. The exact datasheet distinguishes two overload classifications: Low Overload permits 110% of rated output current for 60 s in a 300 s cycle; High Overload permits 150% for 60 s in a 300 s cycle. Both duty classes show 15 kW and 31 A nominal ratings for this specific ordering number. These temporary overload values are not continuous current ratings.

Communication and Configuration

The Siemens datasheet identifies USS and Modbus RTU communication. These are built-in serial communication protocols rather than Ethernet functions; an RJ45-style connection or optional networking capability should not be assumed. The product family provides a built-in basic operator panel for local parameterization and status monitoring as documented by Siemens. Siemens lists four digital inputs, two digital outputs (one relay changeover and one transistor), two analog inputs that may also serve as extra digital inputs, and one analog output. The I/O count is included here for commissioning context, not as a separate ecommerce specification line. Selection of peripheral control devices and communication wiring remains the integrator’s responsibility.

Braking, EMC and Built-in Functions

This precise UV0 ordering code is unfiltered: Siemens explicitly describes the integrated EMC-filter class as “Unfiltered.” A separate external filter may be required for a particular compliance installation, and its selection cannot be assumed from the drive itself. Importantly, the exact-part technical datasheet states that an integrated braking chopper is present. That built-in switching hardware must not be confused with an external braking resistor: resistor provision, compatible values, thermal protection and allowable braking duty must be established from approved Siemens documentation. No resistor is confirmed as included with the inverter. Do not infer safety-certified functions or optional hardware from other V20 variants.

Installation and Typical Applications

The inverter is IP20 / UL open type, with a Siemens FSD frame measuring 240 × 206.5 × 172.5 mm (width × height × depth). It is intended for installation in an appropriate protective electrical enclosure where personnel and the environment cannot contact hazardous live parts. Its listed cooling method is an external fan, and the datasheet gives 1,000 m as the reference installation altitude. Operating ambient is listed as −10 to 60°C with derating-related conditions that must be checked before running at the temperature extremes. The datasheet quotes shielded motor-cable lengths up to 25 m and unshielded lengths up to 50 m; installation and EMC arrangements can change applicability. Suitable engineering applications may include conveyors, pumps, fans, basic mixers and material-handling mechanisms if the connected motor, duty cycle, motor current and system protection match the drive.

Exact Variant Verification

The complete Siemens part number 6SL3210-5BE31-5UV0 identifies a 15 kW, three-phase 380–480 V, unfiltered SINAMICS V20 in the FSD frame. It must not be confused with 6SL3210-5BE31-5CV0, the corresponding integrated-filter model, or with the 11 kW 6SL3210-5BE31-1UV0. The UV0 order code has an integrated braking chopper according to its exact Siemens datasheet despite its older revision suffix. Frame dimensions, current ratings and optional equipment should be checked by exact order number before procurement or replacement.
