Schneider ATV630D37N4 Altivar Process ATV630 37kW 380-480VAC Variable Speed Drive with Embedded Ethernet
| Place of Origin | Germany |
| Brand Name | Schneider Electric |
| Model Number | ATV630D37N4 |
Product Overview
The Schneider ATV630D37N4 is a 37 kW Altivar Process ATV630 variable speed drive for three-phase 380–480 VAC industrial power systems.
It is designed for medium-to-large pumps, fans, compressors, cooling systems, conveyors and plant-utility applications. The ATV630 platform provides embedded Ethernet, process monitoring, energy-management functions and web-based diagnostics.
At this power level, motor current, overload duty, cabinet ventilation, cable sizing and upstream protection must be reviewed before installation.

Compatible System and Applications
The ATV630D37N4 is suitable for water and wastewater pumps, industrial ventilation, cooling-tower fans, compressors, large conveyors and plant-utility systems.
The drive can support process-control strategies based on pressure, flow, level or temperature signals. Controller and network compatibility must be confirmed before integration.
Maintenance and Replacement Notes
Verify the complete ATV630D37N4 reference and the motor current before replacement. Selection should not be based only on the 37 kW value.
Back up motor parameters, process settings, Ethernet configuration, I/O assignments, fault history and firmware before removing the original drive.
Inspect cooling fans, DC-bus components, power terminals, communication ports, grounding and cabinet ventilation on used or replacement equipment.
