Schneider Electric ATV310HD22N4EF Easy Altivar 310 22 kW 380-460V IP20 EMC Filter Variable Frequency Drive

The Schneider Electric ATV310HD22N4EF is a three-phase variable speed drive from the Easy Altivar 310 range, rated 22 kW heavy duty (30 kW normal duty) at a 380-460 V supply. It delivers a continuous output current of 46 A in heavy duty mode, communicates over Modbus RTU through a front-panel RJ45 port, and drives asynchronous motors on simple machines, with an integrated Class C3 EMC filter.

Selection Notes

The ATV310HD22N4EF carries two nameplate ratings on the same frame: 22 kW heavy duty with a 69 A 60 s transient current for constant-torque loads that need overload margin at start, and 30 kW normal duty with a lower 66 A transient margin for variable-torque loads that rarely overload. Pick the heavy duty rating when the driven machine needs the 170-200% transient overtorque headroom; pick the normal duty rating to run the larger 30 kW motor on the same drive frame when the load itself has less starting demand. The integrated Class C3 EMC filter on this variant meets conducted-emission limits without an external filter, at the cost of 9.7 kg versus the lighter non-filtered build. The 22 kA heavy duty short-circuit withstand sets the upstream protective device coordination.
