Line current is 7.3 A at 240 V (8.7 A at 200 V), with an apparent power rating of 4 kVA at 240 V — these figures size the upstream protection and cable. Switching frequency is adjustable from 6 to 16 kHz; above 12 kHz a derating factor applies, so if you need quiet motor operation at 16 kHz, expect to reduce continuous output current. Transient overtorque capability is 120 % of nominal motor torque for 60 seconds — useful for breakaway loads or short-duration overloads. ## Fieldbus and control interface The drive includes a 2-wire RS-485 physical interface supporting Modbus RTU at 9600 or 19200 bps, with addressing from 1 to 247. Optional communication cards add BACnet, LonWorks, Metasys N2, or Apogee FLN — useful for building management system integration. An adjustable PI regulator is built in for closed-loop process control (pressure, flow, level) without an external controller. ## Compliance and environmental limits CE marked and carries a broad set of EMC and safety standards: EN/IEC 61800-3 (environments 1 and 2, categories C1–C3), EN/IEC 61800-5-1, and UL Type 1. Pollution degree 3 per IEC 61800-5-1 means it tolerates conductive pollution in industrial enclosures; operating altitude is limited to 2000 m on corner-grounded networks, up to 3000 m otherwise. Shock resistance is 15 gn for 11 ms per IEC 60068-2-27; relative humidity range is 5–95 % non-condensing.","metaTitle":"Schneider Electric ATV21HU22M3X AC Drive, 2.2 kW","metaDescription":"Schneider Electric ATV21HU22M3X Altivar 21 AC drive, 2.2 kW, 200-240 V 3-phase input, 7.3 A line current, RS-485 Modbus, CE/UL.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["AC Drive (VFD) 240V"],"specifications":{"Depth":"5.9 in (150 mm)","Phase":"3 phase","Width":"4.2 in (107 mm)","Height":"5.6 in (143 mm)","Marking":"CE","Category":"22155-ATV212 1 -
