The Schneider ATV630D55N4 is a 55 kW variable speed drive from the Altivar Process ATV630 series. It is intended for three-phase 380–480 VAC process, infrastructure and plant-utility systems.
The drive provides embedded Ethernet, Modbus serial communication, web-based diagnostics, process PID control and energy-monitoring functions. It is suitable for large pumps, fans, compressors, cooling systems and water-treatment installations.
The ATV630D55N4 should be positioned as a project and replacement product. Installation requires careful verification of motor current, cable sizing, upstream protection, cabinet ventilation and lifting requirements.

The ATV630D55N4 is suitable for large centrifugal pumps, industrial fans, compressors, water and wastewater treatment, cooling plants, conveyors and building-energy systems.
The embedded Ethernet architecture supports integration with compatible industrial controllers and supervisory systems. Network configuration and cybersecurity requirements should be reviewed during commissioning.
Verify the full ATV630D55N4 commercial reference, motor current, supply voltage and duty requirement before ordering.
Back up motor parameters, process setpoints, PID tuning, network settings, I/O assignments, firmware and installed option modules before replacement.
Inspect cooling components, power connections, grounding, Ethernet ports, display terminal and diagnostic history. Packaging and lifting arrangements must also be confirmed.
Adjacent N4 models include ATV630D45N4 and ATV630D75N4.
Models from the ATV650 enclosed range use a different enclosure and installation concept and should not be treated as equivalent ATV630 products.
Please provide the complete existing drive reference, motor nameplate, motor rated current, supply voltage, process application, communication requirements and installation environment.
Product condition, firmware, display-terminal configuration, option modules, testing scope, packaging, availability and delivery time must be confirmed before quotation.
