Product details

The ATV350U22N4W is a basic version drive from the Altivar Machine ATV350 family, sized for 2.2 kW asynchronous or synchronous motors on a 3-phase 400-480 V line. It delivers 8.5 A output current and covers 1-599 Hz output frequency, with a switching frequency adjustable from 2 to 16 kHz (derate current above 2 kHz). Integrated Class C2 EMC filter is good for most industrial environments without an external box. STO (safe torque off) is built in, so no separate safety relay for that function.

Wall-mounted, horizontal orientation. Dimensions: 12.2 in high, 20.6 in wide, 9.2 in deep — fits a standard 600 mm wide enclosure backplate. Natural air cooling (no fan), so keep clearance around the heatsink. Rated for pollution degree 2, 5-95% RH non-condensing, and 1000 m altitude without derating (derate 0.5% per additional 100 m).

Compliance and protection

Marked CE, UL, CULus, IEC, UKCA. Meets IEC 61800-5-1, IEC 61800-3 (environments 1 category C2 and 2 category C3), UL 508C, IEC 60721-3, IEC 61508, and IEC 13849-1. Protection covers line supply phase loss, motor phase loss, over/undervoltage, overheating, motor overload (with PTC probes), short-circuit between motor phases, and overcurrent between output phases and earth.

Internal 24 V DC supply for logic inputs. Discrete inputs are 12 V DC programmable (0-0.8 V low, 11-24 V high). One incremental encoder input (24 V). Physical interface includes two 100BASE-FX Ethernet ports supporting EtherNet/IP. M12 I/O connectors for EtherCAT, EtherNet/IP, Modbus TCP, and PROFINET on the base. IO scanner access method.

Frequently asked questions

What is the closest alternative to ATV350U22N4W in the same family?

The ATV350 family includes variants with different power ratings and integrated options (fieldbus, I/O). The closest functional match is a higher-power sibling in the same mechanical footprint, but the 2.2 kW basic version is the most common for standalone motor control. No pin-compatible drop-in exists with different power; size up or down within the family based on motor kW.

What compliance documentation does Schneider provide for this drive?

The drive carries CE, UL, CULus, IEC, and UKCA markings. It complies with IEC 61800-5-1, IEC 61800-3 (environments 1 category C2 and 2 category C3), UL 508C, IEC 60721-3, IEC 61508, and IEC 13849-1. Standard Schneider declarations and certificates are available through their documentation portal.
