Schneider ATV320U40N4C ATV320 4kW Three-Phase Compact Variable Speed Drive

Product Overview

The Schneider ATV320U40N4C is a 4 kW, 5 HP variable speed drive from the Altivar Machine ATV320 series. It is designed for a 380–500 VAC three-phase supply and uses the compact C-format housing for integration into industrial control cabinets.

The drive is optimized for simple and advanced machine applications requiring high overload capability, accurate motor control, embedded safety functions and flexible communication. It supports asynchronous motors and compatible synchronous or permanent-magnet motors.

The exact ATV320U40N4C reference identifies the U40 power code, N4 voltage class and Compact C-format enclosure. All three elements must be checked during replacement.

Technical Specifications

Compatible System and Applications

The ATV320U40N4C is commonly used in conveyors, packaging machinery, mixers, material-handling equipment, textile machinery, pumps, fans and automated manufacturing systems.

The 4 kW power class is widely used in industrial machines, but final selection must be based on motor rated current, overload torque, acceleration cycle, operating frequency and environmental conditions.

Maintenance and Replacement Notes

Verify the complete ATV320U40N4C reference. ATV320U40N4B is a Book-format model and may not fit the same cabinet layout despite having the same voltage and nominal power.

Back up or record the original drive parameters before replacement. Important settings include motor nameplate values, control mode, speed references, digital and analog I/O, safety inputs, braking parameters and communication configuration.

Check the cooling fan, DC bus, power terminals, control terminals, brake-chopper circuit and installed option cards when evaluating a used drive.

Related Models

ATV320U40N4B is the related Book-format 4 kW N4 drive. Adjacent Compact N4 models include ATV320U30N4C at 3 kW and ATV320U55N4C at 5.5 kW.

ATV320U40M3C is the corresponding 4 kW Compact drive for a 200–240 VAC three-phase supply.

Inquiry and Supply Notes

Please provide the motor nameplate, existing drive model, input supply, required control mode, braking duty, communication network and cabinet installation information.
