Nominal output current is 106 A at 2.5 kHz switching frequency for normal duty; heavy-duty continuous output is 88 A at the same carrier. The 380...480 V three-phase supply range covers common global industrial voltages without a transformer. The integrated braking chopper (standard variant) allows dynamic braking with an external resistor, useful for high-inertia loads or rapid deceleration cycles where DC-bus overvoltage would otherwise trip the drive. IP55 degree of protection and UL Type 1 enclosure mean the drive can be wall-mounted in locations subject to hose-down or dust, without requiring a separate cabinet in many indoor industrial settings. Operating altitude is 1000...4800 m with a 1 % current derating per 100 m above 1000 m — factor this into the installation if the drive sits at elevation. Ambient relative humidity range is 5...95 % non-condensing. Chemical pollution resistance class 3C3 and dust pollution resistance class 3S3 per IEC 60721-3-3 confirm suitability for corrosive or dusty environments typical in wastewater, mining, or chemical processing. ## Control wiring and fieldbus options Control terminals are screw-type, accepting 0.5...1.5 mm² (AWG 20...16). The drive provides an internal 24 V DC supply for digital inputs and STO (21...27 V), plus a 10.5 V DC reference for an external potentiometer. Three option module slots (A, B, C) accept fieldbus adapters for Profibus DP V1, PROFINET, DeviceNet, EtherCAT, CANopen, Ethernet Powerlink, and Ethernet IP / Modbus TCP. Slot B also supports digital or analog encoder interfaces and resolver feedback. Built-in Modbus serial and Ethernet IP / Modbus TCP ports are standard; the drive auto-negotiates half/full duplex on the Ethernet link. Transmission rates include 10/100 Mbit/s for Ethernet and 9600/19200 bit/s for serial. ## Compliance and lifecycle status The drive carries CE marking and complies with UL 508C, IEC 61800-3 (EMC), IEC 61800-5-1 (safety), IEC 61508, and IEC 13849-1 — covering functional safety up to SIL capability for the STO circuit. Electromagnetic compatibility includes immunity test levels 3 and 4 per IEC 61000-4-2 through -4-6, and total harmonic current distortion (THDI) below 48 % at 80...100 % load per IEC 61000-3-12.","metaTitle":"Schneider ATV950D55N4 AC Drive, 55 kW ND, 106 A, 380-480 V","metaDescription":"Schneider Electric ATV950D55N4 Altivar Process drive, 55 kW normal duty / 45 kW heavy duty, 106 A output, IP55, integrated braking chopper, CE marked.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["AC Drive (VFD) 480V"],"specifications":{"title":"ATV950D55N4","Supply":"External supply for digital inputs: 24 V DC (19...30 V), Internal supply for reference potentiometer (1 to 10 kOhm): 10.5 V DC +/- 5 %, Internal supply for digital inputs and STO: 24 V DC (21...27 V), 1 MOhm 500 V DC for 1 minute to earth","Marking":"CE","Variant":"Standard version With braking chopper","Standards":"UL 508C IEC 61800-3 IEC 61800-5-1 IEC 61000-3-12 IEC 60721-3 IEC 61508 IEC 13849-1","EMC filter":"Integrated With EMC plate option","Data format":"8 bits, configurable odd, even or no parity","Noise level":"69.9 dB","description":"variable speed drive, Altivar Process ATV900, ATV950, 55kW, 400 to 480V, with braking unit, IP55","Maximum THDI":"<48 % from 80...100 % of load conforming to IEC 61000-3-12","Exchange mode":"Half duplex, full duplex, autonegotiation Ethernet IP/Modbus TCP","Mounting mode":"Wall mount","Option Module":"Slot A: communication module for Profibus DP V1 Slot A: communication module for PROFINET Slot A: communication module for DeviceNet Slot A: communication module for EtherCAT Slot A: communication module for CANopen daisy chain RJ45 Slot A: communication module for CANopen SUB-D 9 Slot A: communication module for CANopen screw terminals Slot A/slot B/slot C: digital and analog I/O extension module Slot A/slot B/slot C: output relay extension module Slot B: 5/12 V digital encoder interface module Slot B: analog encoder interface module Slot B: resolver encoder interface module communication module for Ethernet Powerlink","Assembly style":"Enclosed","Motor power kW":"55.0 kW for normal duty 45.0 kW for heavy duty","Regulation loop":"Adjustable PID regulator","lifecycle_stage":"current","Pollution degree":"2","Range of product":"Altivar Process ATV900","Shock resistance":"15 gn for 11 ms conforming to IEC 60068-2-27","Relative humidity":"5...95 % without condensation conforming to IEC 60068-2-3","Transmission rate":"10, 100 Mbits 4.8 kbps 9600 bit/s 19200 bit/s","Device application":"Industrial application","Operating altitude":"1000...4800 m with current derating 1 % per 100 m","Operating position":"Vertical +/- 10 degree","Number of addresses":"1...247","Product destination":"Synchronous motors Asynchronous motors","Degree of protection":"UL type 1","Overvoltage category":"III","Type of polarization":"No impedance","Vibration resistance":"1.5 mm peak to peak (f= 2...13 Hz) conforming to IEC 60068-2-6 1 gn (f= 13...200 Hz) conforming to IEC 60068-2-6","Electrical connection":"Control: screw terminal 0.5...1.5 mm²/AWG 20...AWG 16 Motor: screw terminal 70...120 mm²/AWG 1/0...250 kcmil Line side: screw terminal 50...120 mm²/AWG 1...250 kcmil DC bus: screw terminal 50...120 mm²/AWG 1...250 kcmil","Nominal Output Current":"106.0 A","IP degree of protection":"IP55","Network number of phases":"3 phases","Continuous output current":"106 A at 2.5 kHz for normal duty 88 A at 2.5 kHz for heavy duty","Product or component type":"Variable speed drive","[Us] rated supply voltage":"380...480 V","Communication port protocol":"EtherNet/IP Modbus TCP Modbus serial","Environmental characteristic":"Chemical pollution resistance class 3C3 conforming to IEC 60721-3-3 Dust pollution resistance class 3S3 conforming to IEC 60721-3-3","Product specific application":"Process for industrial","Electromagnetic compatibility":"Electrostatic discharge immunity test level 3 conforming to IEC 61000-4-2 Radiated radio-frequency electromagnetic field immunity test level 3 conforming to IEC 61000-4-3 Electrical fast transient/burst immunity test level 4 conforming to IEC 61000-4-4 1.2/50 µs -
