Product details

45 kW / 37 kW heavy-duty VFD for the ATV340 Machine series

The Schneider Electric ATV340D37N4E is a 45 kW normal-duty / 37 kW heavy-duty variable frequency drive from the Altivar Machine ATV340 series, designed for three-phase 380-480 V supply with integrated Class C3 EMC filter. Rated line current at 380 V with internal line choke is 79.8 A for normal duty and 67.1 A for heavy duty; at 480 V it draws 69.1 A normal duty and 59.0 A heavy duty. The drive is wall-mountable, measures 26.0 x 8.4 x 10.3 inches (660 x 213 x 262 mm), and uses forced convection cooling with an integrated heat sink.

Protection, fieldbus, and switching frequency

Protection coverage includes thermal protection, safe torque off, motor phase loss, overcurrent, short-circuit, DC bus overvoltage, line supply over/undervoltage, and input supply loss — all on both motor and drive sides. Switching frequency is adjustable from 2 to 16 kHz, with derating required above 4 kHz. Fieldbus options include PROFINET, DeviceNet, CANopen, EtherCAT, and Modbus TCP/RTU via optional communication modules; the drive has three RJ45 ports and a 2-wire RS 485 physical interface. Compliance covers IEC 61800-3, IEC 61800-5-1, IEC 60721-3, IEC 61508, IEC 13849-1, UL 618000-5-1, and UL 508C, with CE marking.
