The Schneider Electric ATV950D55N4E is a 55 kW class Altivar Process 950 variable speed drive, engineered for demanding industrial motor control applications that require high overload capacity, process stability, and advanced communication features.
It is widely deployed in mining operations, water and wastewater treatment plants, oil & gas systems, conveyors, crushers, extruders, and heavy manufacturing lines. The drive is designed for continuous operation in harsh environments where uptime and torque precision are critical.
With its IP55-rated enclosure and integrated switching architecture, it supports wall-mounted installation close to machinery, enabling decentralized system layouts and reducing the need for large control cabinets.
