The Schneider ATV212WU55N4CZH28 is a 5.5 kW (7.5 hp) variable speed drive from the Altivar 212 family, sized for standard asynchronous motors on 380-480 V three-phase supply. The 11 A line current at 380 V (8.7 A at 480 V) sets the upstream protection and cable sizing — a C1 integrated EMC filter is already onboard, so no external filter is needed for conducted emissions compliance in most industrial environments. The drive carries an adjustable switching frequency of 6 to 16 kHz; above 12 kHz you derate the output current, which matters if you are running a long motor cable or a motor with high capacitive coupling to ground.
Integration and fieldbus fit
Mounts vertically (±10°) with the heat sink clear of enclosures — the 230 mm width and 340 mm height fit a standard 600 mm panel backplate with room for the required top/bottom cable gland clearance. The 208 mm depth includes the heat sink; account for bending radius of the motor and line cables behind the drive. Communication is via the built-in 2-wire RS 485 Modbus RTU port (RJ45 plus open-style connector) at 9600 or 19200 bps, addressing up to 247 nodes. An optional LonWorks communication card plugs in for building-management-system integration.
The ATV212WU55N4CZH28 is classified at a mature lifecycle stage — still available but not a new-design target. For a GMP-validated line where change control is critical, the CE marking and full EN/IEC 61800-3 compliance suite provide the documented emissions and immunity profile needed for an IQ/OQ package.
