Technical Specifications

Compatible System and Applications

The ATV610D55N4 is suitable for large centrifugal pumps, industrial fans, compressors, water and wastewater installations, cooling systems, large conveyors and building-energy plants.

The 55 kW rating applies to Normal Duty. Applications requiring 150% short-term overload should be evaluated using the 45 kW Heavy Duty rating and 88 A continuous output current.

At this power level, installation engineering must include cable sizing, short-circuit protection, cabinet ventilation, heat dissipation, grounding and lifting or handling arrangements.

Maintenance and Replacement Notes

Verify the full ATV610D55N4 commercial reference, display-terminal requirement, frame size, motor duty and output-current requirement.

ATV610D55N4Z is supplied without the display terminal and should be quoted as a separate commercial reference.

Inspect the cooling system, DC-bus capacitors, bus connections, power terminals, display, communication terminals and cabinet airflow. Parameter backup and a powered motor test are recommended before replacement.
