Product Overview

The Schneider ATV320D15N4C is a 15 kW, 20 HP variable speed drive from the Altivar Machine ATV320 series. It operates from a 380–500 VAC three-phase supply and uses the compact C-format enclosure.

This model is designed for demanding industrial machinery requiring high-performance motor control, overload capability, integrated functional safety, dynamic braking support and flexible industrial networking.

The exact ATV320D15N4C reference identifies the D15 power rating, N4 supply-voltage class and Compact C-format construction. These codes must be matched during replacement and quotation.

Technical Specifications

Compatible System and Applications

The ATV320D15N4C is suitable for larger conveyors, mixers, packaging and production lines, material-handling machinery, textile equipment, pumps, fans and other 15 kW industrial machine applications.

The drive must be selected using the motor rated current, required overload torque, acceleration and deceleration time, operating speed range, regenerative energy and number of operating cycles.

Maintenance and Replacement Notes

Verify the full ATV320D15N4C model and do not identify the drive only as ATV320D15N4. The final C suffix defines the compact enclosure and affects cabinet fit, cooling and terminal arrangement.

Record the original parameter file and all installed option modules before replacement. Check motor-control parameters, I/O assignments, safety functions, communication settings and braking configuration during commissioning.

For used drives, inspect the cooling fan, power section, DC-bus capacitors, main terminals, control board, brake-chopper circuit and stored fault history.

Related Models
