The ATV21HU55M3X is a 5.5 kW Altivar 21 variable frequency drive for asynchronous motors on 200-240 V three-phase supply. Line current draws 17.3 A at 240 V (20.8 A at 200 V), apparent power 9.2 kVA. Switching frequency is adjustable 6-16 kHz, with derating above 12 kHz. Transient overtorque capability is 120% of nominal motor torque for 60 seconds — enough for short-duration overloads on conveyors or pumps.
This drive is classified as mature in its lifecycle.
CE marked. Complies with IEC 61800-3 for EMC in environments 1 and 2, categories C1, C2, C3, and with EN 61800-5-1 for safety. Pollution degree 3 per IEC 61800-5-1. Dielectric strength tested at 2830 V DC between earth and power terminals, 4230 V DC between control and power terminals. Operating altitude limited to 2000 m for corner-grounded distribution networks.
