- Description
The Schneider Electric ATV310HU55N4E is a variable frequency drive from the Easy Altivar 310 range, built for simple machines on a 380-460 V three-phase supply. In heavy duty it delivers 12.6 A continuous output for 5.5 kW motors (16.0 A / 7.5 kW in normal duty). It includes an integrated Modbus RS485 port, sensorless vector control, and IP20 protection with an integrated cooling fan.

Selection Notes
The heavy-duty rating (12.6 A continuous, 5.5 kW) suits variable-torque loads such as pumps and fans, where overload margin matters less than continuous current headroom. The normal-duty rating (16.0 A, 7.5 kW) on the same frame suits constant-torque loads that draw more current continuously. Sensorless vector control is available alongside standard V/f control for applications needing better torque at low speed than open-loop V/f alone provides. The drive ships without an EMC filter, so external filtering is needed where EN 61800-3 conducted-emission limits apply.
