Siemens SINAMICS V20 6SL3210-5BE23-0CV0 3 kW 3-Phase VFD

Product Overview

The Siemens SINAMICS V20 6SL3210-5BE23-0CV0 is a basic variable frequency drive designed for adjustable-speed control of suitable three-phase AC motors. This exact CV0 variant has a 3.0 kW (4.0 HP manufacturer rating) output at the documented duty classifications and uses a three-phase 380–480 V AC supply. Its integrated EMC filter is identified as Class A in the manufacturer datasheet and as Category C3 in Siemens’ product listing. An integrated braking chopper is not specified for this original CV0 version.

Electrical Ratings

The required supply is three-phase 380–480 V AC, with Siemens specifying a -15%/+10% permitted variation and an input frequency of 47–63 Hz. The drive provides a three-phase output with a nominal 400 V IEC rating. Rated power is 3.00 kW in both High Overload and Low Overload duty. Rated continuous output current is 7.30 A for both modes at the stated 400 V and 480 V rating bases. Its configurable output frequency range is 0–550 Hz; the maximum permitted motor and machine speed must be determined independently from the motor and application documentation. Motor selection should match motor nameplate voltage, current, installation and duty requirements.

Control Modes and Performance

The SINAMICS V20 family is intended for basic variable-speed motor control, with commissioning parameters and drive functions set through its built-in basic operator panel. Siemens specifies 110% of rated output current for 60 seconds in Low Overload mode and 150% for 60 seconds in High Overload mode, each with a 300-second overload cycle. These are temporary limits, not continuous output-current ratings. The two overload classifications must not be combined to overstate available continuous power. Detailed control methods and motor compatibility should be checked against the applicable operating instructions and motor design before specifying specialized operation.

Communication and Configuration

Siemens lists USS and Modbus RTU as the integrated communication protocols for this exact part number. These are serial industrial communication functions; their availability does not imply that the drive contains an Ethernet port or supports Ethernet-based fieldbus protocols. The Siemens product listing confirms a built-in BOP (basic operator panel). The drive also includes four standard digital inputs, two digital outputs (one relay changeover contact and one transistor output), two analog inputs that may also serve as additional digital inputs, and one analog output. The interface counts are included here for configuration context rather than as separate ecommerce technical specification rows. Required controllers, parameter settings, cables and other system components must be selected separately.

EMC Filter and Braking

This CV0 variant incorporates EMC filtering: Siemens describes it as C3 in the catalogue listing and Class A in the exact-model datasheet. Compliance depends on the complete installation, cabling, earthing, and applicable EMC environment. The product listing does not describe an integrated braking unit on CV0, whereas it explicitly identifies the later CV1 successor as a version with an integrated braking unit. Accordingly, no integrated braking chopper is claimed for 6SL3210-5BE23-0CV0. No external braking resistor is confirmed as included. Applications requiring frequent deceleration, high-inertia stopping or regenerative energy management need a separate engineering review.

Installation and Typical Applications

The enclosure is IP20 / UL open type and normally requires appropriate electrical cabinet protection and qualified installation. Siemens identifies an FSB housing measuring 140.0 × 160.0 × 164.5 mm (width × height × depth). The datasheet lists external-fan cooling, a reference installation altitude of 1,000 m, operating ambient temperature of -10 to 60 °C subject to conditions and derating, and maximum relative humidity of 95%. Maximum documented motor cable lengths are 25 m shielded and 50 m unshielded. These constraints, along with protective devices, cable routing, ventilation and EMC requirements, must be reviewed against the installation manual.

For a correctly sized motor and mechanical load, technically appropriate uses may include pumps, ventilation fans, conveyor drives, small material-handling systems, and basic industrial speed-control duties. Appropriate overload margin, braking requirements, motor cooling at reduced speed, and the environment must be evaluated per application. This description does not guarantee compatibility with every motor or machine.

Exact Variant and Lifecycle Verification

The full order number 6SL3210-5BE23-0CV0 identifies a 3.0 kW, three-phase 380–480 V, C3-filtered SINAMICS V20 CV0 drive. Siemens lists phase-out effective 10 February 2025 and names 6SL3210-5BE23-0CV1 as its successor. The successor’s integrated braking unit is not a feature of this CV0 product. Verify the complete label and electrical data before replacement; the last characters of the order number matter for hardware compatibility.
