Continuous output current is 12.7 A at 4 kHz for normal duty, 9.3 A at 4 kHz for heavy duty. The IP55 enclosure with UL type 12 rating suits washdown or dusty environments without a separate cabinet. Built-in braking chopper handles regenerative loads; the load break switch provides local disconnection for safe maintenance. Control supply is 24 V DC (19...30 V) for digital inputs, with an internal 10.5 V DC reference for a 1 to 10 kOhm potentiometer and a separate 24 V DC (21...27 V) supply for STO and digital inputs. ## Integration notes Mount vertically within ±10 degrees. Wall-mount only. Control wiring uses screw terminals accepting 0.5...1.5 mm²; power terminals accept 4...6 mm² on line and motor sides, 2.5...6 mm² on DC bus. Communication ports support Modbus TCP, EtherNet/IP, and Modbus serial at 10/100 Mbit/s, plus 4.8 kbps, 9600, and 19200 bit/s for serial. Slot A accepts optional Profibus DP V1, PROFINET, DeviceNet, EtherCAT, CANopen, or Ethernet Powerlink modules. Integrated EMC filter meets IEC 61800-3; an optional EMC plate is available for higher performance. Operating altitude up to 1000 m without derating, then 1 % per 100 m to 4800 m. Ambient humidity 5...95 % non-condensing. CE marked. Complies with UL 508C, IEC 61800-3 (EMC), IEC 61800-5-1 (safety), IEC 61000-3-12 (harmonic), IEC 60721-3 (environmental), IEC 61508, and IEC 13849-1 (functional safety). Chemical resistance class 3C3 and dust resistance class 3S3 per IEC 60721-3-3.","metaTitle":"Schneider Electric ATV950U55N4EU Altivar Process Drive, 5.5","metaDescription":"Schneider Electric ATV950U55N4EU variable speed drive, 380-480 V 3-phase, 5.5 kW normal duty, IP55, with braking chopper and load break switch.
