Schneider ATV650D22N4 Altivar Process ATV650 22kW 380-480VAC IP55 Wall-Mounted Variable Speed Drive
| Place of Origin | Germany |
| Brand Name | Schneider Electric |
| Model Number | ATV650D22N4 |
Product Overview
The Schneider ATV650D22N4 is a 22 kW, 30 HP Normal Duty variable speed drive from the Altivar Process ATV650 series. It is designed for three-phase 380–480 VAC process systems and features an IP55 wall-mounted enclosure.
The ATV650D22N4 is intended for pumps, cooling-tower fans, compressors, water-treatment systems, HVAC equipment and plant utilities. It provides embedded Ethernet, Modbus serial communication, process-control functions, energy monitoring and web-based diagnostics.
The 22 kW power value is the Normal Duty classification. Heavy Duty power, continuous output current and overload capability must be checked against the exact datasheet and the installed motor.

Compatible System and Applications
The ATV650D22N4 is suitable for industrial pumps, cooling-tower fans, compressors, water and wastewater treatment, HVAC systems, process conveyors and general plant utility equipment.
Its IP55 wall-mounted enclosure is intended for process environments where improved resistance to dust and moisture is required. Environmental limits, gland arrangement and ventilation must still be confirmed.
At this power level, installation engineering must include cable sizing, upstream protection, heat dissipation, grounding, motor current and required overload capacity.
Maintenance and Replacement Notes
Verify the complete ATV650D22N4 commercial reference, IP55 enclosure, motor current and duty mode before ordering.
Record the motor parameters, PID configuration, multi-pump logic, Ethernet addressing, Modbus settings, I/O assignments, firmware and fault history.
Inspect enclosure seals, cooling fans, power connections, communication ports, display terminal and internal components when evaluating used or replacement equipment.
