At 380 V it draws 41.6 A line current; at 480 V that drops to 33.1 A, which matters when sizing branch circuit protection for the 480 V installs common in North American panels. Switching frequency is adjustable from 6 to 16 kHz, but above 8 kHz a derating factor applies — the 8-16 kHz band is where you trade motor noise for reduced continuous output current. ## Panel fit and integration constraints The drive measures 28.3 inches tall by 11.2 inches wide and 12.4 inches deep, with a vertical mounting requirement of ±10 degrees. The depth is the dimension that catches people out in shallow enclosures — 315 mm means a standard 400 mm deep cabinet leaves just 85 mm for wiring clearance behind the heat sink. Operating altitude is limited to 1000 m standard, with derating up to 3000 m — but the Corner Grounded distribution network restriction caps at 2000 m. Pollution degree 3 per IEC 61800-5-1 means it tolerates conductive pollution in industrial environments, but not direct washdown. ## EMC compliance and communication options A Class A EMC filter is integrated, meeting EN 61800-3 Category C3 for second environment (industrial) and Category C2 for first environment with additional mitigation. The drive also complies with EN 55011 Class A Group 1 — expect to add an external filter if the installation requires residential limits. Communication is via 2-wire RS-485 Modbus RTU at 9600 or 19200 bps, addressing up to 247 nodes. Optional communication cards support BACnet, LonWorks, Metasys N2, and APOGEE FLN for building management system integration — common in HVAC retrofit work where this drive sees heavy use.","metaTitle":"Schneider Electric ATV21WD22N4 AC Drive, 22 kW, 380-480 V","metaDescription":"Schneider Electric ATV21WD22N4 Altivar 21 AC drive, 22 kW, 3-phase 380-480 V input.
