Product details

75 kW VFD for asynchronous motors

The ATV21WD75N4C is a 75 kW AC drive from the Altivar 21 range, designed for three-phase asynchronous motors on a 380-480 V supply. It delivers 105.3 kVA apparent power at 380 V and draws 141.8 A line current at 380 V or 111.3 A at 480 V. The integrated Class B EMC filter and compliance with IEC 61800-3 category C1 through C3 mean this drive can be installed in first-environment (residential) and second-environment (industrial) networks without an external filter in most cases — a real time-saver during panel commissioning.

Switching frequency and derating

The switching frequency is adjustable from 6 to 16 kHz, with a derating factor applied above 8 kHz. For a 75 kW motor driving a fan or pump, running at 6-8 kHz keeps the drive within its thermal envelope without derating; pushing to 16 kHz quiets the motor but reduces continuous output current — plan the panel cooling accordingly.

Frequently asked questions

What compliance documentation does Schneider Electric provide for ATV21WD75N4C?

The drive carries CE marking and complies with IEC 61800-5-1 (safety), EN 61800-3 (EMC), and EN 55011 Group 1 Class B. The integrated Class B EMC filter covers conducted emissions for first-environment installations. RoHS and REACH declarations are standard with the product documentation.
