Product Overview

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.
