Schneider Electric ATV630D18N4 Altivar Process ATV630 18.5 kW 380-480 V 3-Phase IP21 Variable Frequency Drive

The Schneider Electric ATV630D18N4 variable speed drive is an Altivar Process ATV630 unit rated 18.5 kW normal duty (15 kW heavy duty), delivering 39.2 A continuous output current at 4 kHz from a 380-480 V three-phase supply. It feeds 3-phase asynchronous and synchronous motors and mounts as an IP21, UL Type 1 wall-mount unit for water and wastewater, mining and minerals, oil and gas, and food and beverage process applications.

Selection Notes

Pick the normal-duty rating when the load is variable-torque (fan, pump, compressor) and only needs the standard 120% overload; the heavy-duty rating trades continuous current for the deeper 150% overload constant-torque loads such as conveyors and mixers need. It shares its mounting frame and IP rating with the adjacent kW steps in the ATV630 lineup, so the choice between them comes down to the motor's continuous current draw rather than the enclosure.

Applications

Schneider lists this Altivar Process ATV630 rating for water and wastewater pumps, screw and centrifugal compressors, conveyors and mixers, mining and minerals fans and pumps, oil and gas electro-submersible and jet-fuel pumps, and food and beverage pumps and fans.
