Siemens SINAMICS V20 6SL3210-5BE24-0CV0 4 kW 3-Phase VFD

Overview

The Siemens SINAMICS V20 6SL3210-5BE24-0CV0 is a 4.0 kW, three-phase-input variable frequency drive for controlling an appropriately rated AC motor. This exact CV0 order variant belongs to the 380–480 V AC supply class and has an integrated EMC filter. The published Siemens data identifies a 5 HP NEC rating, IP20 / UL open-type protection, and FSB construction. Selection should be based on the connected motor nameplate, its load profile, the supply system and installation conditions.

Electrical Ratings

This drive accepts 3-phase 380–480 V AC at 47–63 Hz; the manufacturer gives a permitted line-voltage tolerance of −15%/+10%. The output is three-phase, with 400 V IEC and 480 V NEC nominal ratings and a programmable 0–550 Hz output-frequency range. Siemens publishes a rated output current of 8.80 A at the IEC 400 V basis and 8.20 A at the 480 V NEC basis. Low Overload and High Overload both list 4.00 kW motor power; the 5.00 HP designation belongs to the manufacturer-listed NEC rating. These are not interchangeable current values and output frequency alone does not establish safe motor speed.

Control Modes and Performance

Siemens lists Low Overload at 110% of rated output current for 60 seconds and High Overload at 150% for 60 seconds, each with a 300-second cycle. The continuous current must not be confused with these temporary overload limits. Check the duty cycle, motor thermal protection, acceleration demands and any required derating before choosing the drive. SINAMICS V20 provides configurable general-purpose motor control, but a project requiring precise positioning or a safety-rated function must be assessed against documented capabilities and supplementary devices.

Communication and Configuration

The published integrated fieldbus protocols are USS and Modbus RTU. These are serial communication protocols; they do not imply an integrated Ethernet interface. Siemens identifies a built-in basic operator panel (BOP) for commissioning and local parameter setting. The manufacturer product listing also names four digital inputs, two digital outputs, two analog inputs and one analog output. External equipment, engineering tools or communication accessories must be confirmed separately when required by the application.

EMC, Braking and Built-in Functions

This CV0 version has an integrated EMC filter described as Class A in the exact datasheet and as C3 in the Siemens catalogue description. These descriptions refer to different classification wording and are retained with their source context. Importantly, the exact CV0 datasheet says that an integrated braking chopper is NOT provided. Do not treat the braking unit shown for the successor CV1 as a feature of this model; neither a braking chopper nor an external braking resistor is established as included. Check EMC installation requirements, cable screening, grounding and any needed external braking equipment before commissioning.

Installation and Typical Applications

The frame is FSB, 140 × 160 × 164.5 mm (width × height × depth), with IP20 / UL open-type protection. Siemens specifies external fan cooling, installation altitude of 1,000 m and an operating ambient range of −10 °C to 60 °C subject to temperature derating (including at 40 °C or above). The manufacturer lists maximum motor-cable lengths of 25 m shielded or 50 m unshielded under its stated conditions. Mount the drive inside an appropriate protective enclosure, maintain the required ventilation and verify supply protection and earthing. Suitable engineering candidates include compatible small conveyors, fans, pumps and general machine drives where motor current, load profile and environmental limits are satisfied; these examples are application suggestions, not guarantees of suitability.

Exact Variant Verification

The order identifier 6SL3210-5BE24-0CV0 is essential. The CV0 variant is the filtered 4 kW model WITHOUT an integrated braking chopper. Siemens states that this model entered product phase-out on 10 February 2025 and names 6SL3210-5BE24-0CV1 as its successor. The CV1 successor adds an integrated braking unit; its hardware must not be silently assigned to CV0. Confirm the complete order code on the nameplate before replacement or specifying accessories.
