Danfoss VACON0020-3L-0031-4 VACON 20 Compact AC Drive 380-480VAC 15kW 31A MI5
Product Overview
The Danfoss VACON0020-3L-0031-4 is a high-capacity model within the VACON 20 compact variable frequency drive series. It is intended for three-phase 380-480 VAC motor-control systems and is rated for approximately 15 kW or 20 HP motors.
The drive provides a nominal rated current of 31 A and uses the MI5 mechanical frame. It is relevant to industrial pumps, large fans, conveyors, compressors, mixers and process machinery requiring adjustable speed and controlled motor operation.
Because this is one of the larger VACON 20 compact-drive ratings, cabinet dimensions, ventilation, power-cable routing and maintenance clearances should be checked carefully before installation.

Compatible System and Applications
The VACON0020-3L-0031-4 can be used in industrial pumps, ventilation systems, conveyors, compressors, material-handling machinery, process skids and other applications with compatible 380-480 VAC motors.
The drive should be selected according to motor current and load duty. High-inertia machinery, frequent acceleration or rapid deceleration may require additional engineering review, including braking requirements and thermal loading.
Verify control-system integration, including PLC commands, analog speed references, digital inputs, relay outputs, interlocks and fault-response logic.
Maintenance and Replacement Notes
Before replacement, compare the full original type designation, frame, motor current, supply voltage and installed accessories. A similar VACON 20 power rating from another voltage class is not a direct substitute.
Back up the parameter file and document the existing wiring. Confirm motor data, frequency limits, ramp times, current limits, control mode, analog scaling and terminal assignments.
The iC2-Micro family may be considered as an engineering migration option, but conversion requires verification of mounting dimensions, electrical terminals, I/O functions, communication, braking and application parameters.
Related Models
Related 380-480 VAC models include VACON0020-3L-0023-4 and VACON0020-3L-0038-4.
The VACON0020-3L-0031-2 has the same current code but belongs to the 208-240 VAC voltage class. The two models must not be treated as voltage-compatible alternatives.
