Product details

The Schneider Electric ATV32HU55N4437 is an Altivar 32 variable speed drive rated for 5.5 kW (7.5 hp) motor loads on a 380-480 V three-phase supply. It comes with an integrated Class C2 EMC filter, which means it meets EN 61800-3 Category C2 conducted emissions limits out of the box — no external filter needed for most industrial panel installations. The drive draws 20.7 A line current at 380 V and 14.5 A at 500 V, so you can size the upstream protection accordingly.

Fieldbus & Integration

The drive supports CANopen, DeviceNet, EtherNet/IP, and Profibus DP V1 via optional communication cards. A front-panel RJ45 connector handles Modbus or CANopen daisy-chain. The built-in PID regulator handles closed-loop process control without an external controller.

Protection & Diagnostics

Onboard diagnostics include separate LEDs for drive voltage, Bluetooth status, CANopen run/error, and drive fault. The drive protects against input phase loss, output short-circuits, earth faults, and overheating — all managed internally without external modules.

Frequently asked questions
