Rated line current at 380 V with internal line choke is 79.8 A for normal duty and 67.1 A for heavy duty; at 480 V it draws 69.1 A normal duty and 59.0 A heavy duty. The drive is wall-mountable, measures 26.0 x 8.4 x 10.3 inches (660 x 213 x 262 mm), and uses forced convection cooling with an integrated heat sink. ## Protection, fieldbus, and switching frequency Protection coverage includes thermal protection, safe torque off, motor phase loss, overcurrent, short-circuit, DC bus overvoltage, line supply over/undervoltage, and input supply loss — all on both motor and drive sides. Switching frequency is adjustable from 2 to 16 kHz, with derating required above 4 kHz. Fieldbus options include PROFINET, DeviceNet, CANopen, EtherCAT, and Modbus TCP/RTU via optional communication modules; the drive has three RJ45 ports and a 2-wire RS 485 physical interface. Compliance covers IEC 61800-3, IEC 61800-5-1, IEC 60721-3, IEC 61508, IEC 13849-1, UL 618000-5-1, and UL 508C, with CE marking.","metaTitle":"Schneider Electric ATV340D37N4E Altivar Machine VFD, 45 kW","metaDescription":"Schneider Electric ATV340D37N4E Altivar Machine ATV340 VFD, 45 kW normal duty / 37 kW heavy duty, 3-phase, 380-480 V, IP20, wall mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["AC Drive (VFD) 480V"],"specifications":{"Depth":"10.3 in (262.0 mm)","Phase":"3 phase","Width":"8.4 in (213.0 mm)","title":"ATV340D37N4E","Height":"26.0 in (660.0 mm)","Marking":"CE","Variant":"Standard version","Category":"US1CP4B22183","Isolation":"Between power and control terminals","Standards":"IEC 61800-3 IEC 61800-5-1 IEC 60721-3 IEC 61508 IEC 13849-1 UL 618000-5-1 UL 508C IEC 61000-3-12","EMC filter":"Class C3 EMC filter integrated","Data format":"8 bits, configurable odd, even or no parity","Noise level":"63.5 dB","Option card":"communication module, PROFINET communication module, DeviceNet communication module, CANopen communication module, EtherCAT","description":"variable speed drive, Altivar Machine ATV340, 37kW, heavy duty, 400V, 3 phases, Ethernet","Line current":"79.8 A 380 V with internal line choke normal duty) 69.1 A 480 V with internal line choke normal duty) 67.1 A 380 V with internal line choke heavy duty) 59 A 480 V with internal line choke heavy duty) 67.1 A 59.0 A","Maximum THDI":"<48 % 80 % load IEC 61000-3-12","Mounting Mode":"Wall mount","Apparent power":"57.4 kVA 480 V normal duty) 49.1 kVA 480 V heavy duty)","Assembly style":"With heat sink","Connector Type":"3 RJ45","Motor power kW":"45 kW normal duty 37 kW heavy duty","Output voltage":"<= power supply voltage","Protection type":"Thermal protection motor Safe torque off motor Motor phase loss motor Thermal protection drive Safe torque off drive Overheating drive Overcurrent drive Output overcurrent between motor phase and earth drive Output overcurrent between motor phases drive Short-circuit between motor phase and earth drive Short-circuit between motor phases drive Motor phase loss drive DC Bus overvoltage drive Line supply overvoltage drive Line supply undervoltage drive Input supply loss drive Exceeding limit speed drive Break on the control circuit drive","Regulation loop":"Adjustable PID regulator","Type of cooling":"Forced convection","lifecycle_stage":"current","Method of access":"Slave Modbus RTU Slave Modbus TCP","Pollution degree":"2 IEC 61800-5-1","Range of Product":"Altivar Machine ATV340","Supply frequency":"50...60 Hz +/- 5 %","Relay output type":"Relay outputs R1A Relay outputs R1C 100000 cycles Relay outputs R2A Relay outputs R2C 100000 cycles","Transmission Rate":"4.8 kbit/s 9.6 kbit/s 19.2 kbit/s 38.4 kbit/s","Operating altitude":"<= 4800 m with current derating above 1000m","Operating position":"Vertical +/- 10 degree","Physical interface":"2-wire RS 485","Transmission frame":"RTU","Analogue input type":"AI1 software-configurable current 0...20 mA 250 Ohm 12 bits AI1 software-configurable temperature probe or water level sensor AI1 software-configurable voltage 0...10 V DC 31.5 kOhm 12 bits AI2 software-configurable voltage -
