The Schneider Electric ATV950D55N4 is a 55 kW class variable speed drive from the Altivar Process 950 series, designed for heavy industrial applications requiring high power motor control, stable torque output, and integrated process monitoring.
It is widely used in mining operations, water treatment systems, oil & gas facilities, conveyors, crushers, mixers, and large-scale industrial automation systems. The drive is engineered for continuous-duty operation in demanding environments where reliability and process stability are critical.
With its IP55 protection rating, it can be installed in more exposed industrial locations, supporting decentralized system designs and reducing reliance on fully enclosed electrical cabinets.
