Drive fit for a 30 kW, 200-240 V three-phase line
The ATV21HD30M3X is a 30 kW Altivar 21 AC drive designed for three-phase 200-240 V input — the line current draws 89.5 A at 240 V and 113.3 A at 200 V, so the upstream feeder and branch protection must be sized for the lower-voltage end of the range. Apparent power is 44.6 kVA at 240 V, which sets the transformer or generator capacity needed for a single drive installation.
Switching frequency and torque capability
Switching frequency is adjustable from 6 to 16 kHz, with derating required above 8 kHz — for a 30 kW motor driving a fan or pump, 6 kHz keeps the IGBT junction temperature within limits while the 16 kHz ceiling quiets motor whine on constant-torque loads. Transient overtorque of 120 % for 60 seconds gives headroom for breakaway torque on conveyors or crushers without oversizing the drive frame.
Compliance and environmental ratings
The drive carries CE marking and complies with IEC 61800-5-1 (safety) and IEC 61800-3 (EMC) for environments 1 and 2, categories C1 through C3 — it ships without an EMC filter, so a line-side filter may be needed for first-environment (residential) installations. Pollution degree 3 per IEC 61800-5-1 means the drive is rated for conductive pollution environments — typical in industrial panels near machining or chemical processes — and the IP20 enclosure requires cabinet mounting.
