Schneider ATV650U40N4 Altivar Process ATV650 4kW 380-480VAC IP55 Wall-Mounted Variable Speed Drive
| Place of Origin | Germany |
| Brand Name | Schneider Electric |
| Model Number | ATV650U40N4 |
Product Overview
The Schneider ATV650U40N4 is a 4 kW, 5 HP Normal Duty variable speed drive from the Altivar Process ATV650 series. It is designed for three-phase 380–480 VAC industrial power systems and uses an IP55 wall-mounted enclosure for process and infrastructure applications.
The ATV650 platform combines motor-speed control with embedded Ethernet communication, process PID functions, multi-pump control, energy monitoring and web-based diagnostics. The high-protection enclosure makes the drive suitable for locations where a standard open cabinet drive may not provide sufficient environmental protection.
The 4 kW rating is the Normal Duty motor-power classification. Heavy Duty motor power and continuous output current must be confirmed from the exact product datasheet and the actual motor load.

Compatible System and Applications
The ATV650U40N4 is suitable for small pumps, ventilation fans, water-treatment equipment, HVAC systems, compressors, conveyors and general process machinery.
Its IP55 enclosure supports wall-mounted installation in dusty, humid or process environments, subject to the specified ambient conditions and installation requirements.
Final selection must consider motor rated current, Normal Duty or Heavy Duty operation, acceleration time, process load, ambient temperature, altitude, cable length and required communication protocol.
Maintenance and Replacement Notes
Verify the complete ATV650U40N4 commercial reference. Do not replace it using only the shortened ATV650U40 designation because the N4 suffix identifies the three-phase 380–480 VAC supply group.
Before replacement, record the motor data, process PID settings, multi-pump configuration, Ethernet addressing, Modbus parameters, I/O assignments, firmware and installed option modules.
For used equipment, inspect the enclosure seals, cooling fans, power terminals, Ethernet ports, display terminal, DC-bus components and stored fault history.
Related Models
Adjacent ATV650 N4 references include ATV650U30N4 at 3 kW, ATV650U55N4 at 5.5 kW and ATV650U75N4 at 7.5 kW.
ATV630U40N4 uses a different enclosure and installation concept and should not be treated as the same product.
Inquiry and Supply Notes
Please provide the complete existing drive reference, motor nameplate, motor rated current, supply voltage, process application and required communication network.
Heavy Duty rating, output current, display-terminal package, firmware, EMC requirements, braking configuration, product condition, testing scope, availability and delivery time must be confirmed before quotation.
