The reference in one paragraph
The ATV320U07N4C is a compact-book Altivar Machine ATV320 variable speed drive rated 0.75 kW / 1 hp for heavy duty at 380…500 V three-phase (-15…+10%). Per the official Schneider product datasheet, it delivers 2.3 A continuous output current at 4 kHz (heavy duty) with 3.5 A available for 60 s, and it integrates both Modbus and CANopen communication with a class C2 EMC filter. The ATV320 family targets industrial machines, and this size is the entry point of the range.

Decoding the ordering number
In the official designation, U07 corresponds to the 0.75 kW power size, and N4 to the 380…500 V three-phase supply range with the C denoting the compact book format. Note that this voltage window is family-specific: on the Altivar 610 family the N4 code corresponds to 380…460 V instead. When migrating between families, match the datasheet value of the exact reference, not the suffix pattern.
What to confirm before ordering
Confirm the complete reference against your failed unit's nameplate (the suffix carries voltage, power and format); the control profiles your application needs — the ATV320 offers sensorless flux vector as standard, which matters for crane and hoist retrofits; the STO wiring plan if your machine uses safety functions (STO SIL 3 is integrated); and the cabinet's ambient temperature, since continuous ratings above 50 °C require derating. We verify the full reference free of charge from a nameplate photo via the RFQ form.

Frequently Asked Questions
What is the difference between ATV320U07N4C and U07N4B references?
The trailing letter encodes the format/feature variant within the family, and the official datasheet for each exact reference lists its rating, format and integrated options. Match the complete ordering number — not just the power code — against your existing unit before ordering, and send us the nameplate if unsure.
Can the ATV320U07N4C run a 500 V supply?
Yes: the official rating spans 380…500 V three-phase (-15…+10%). At 500 V the official heavy-duty line current is 2.4 A, with 2.1 kVA apparent power; at 380 V it is 3.2 A. Check your supply against the window before installation.
Does this drive include a safety function?
The ATV320U07N4C integrates STO (safe torque off) at SIL 3 per the official datasheet, plus extended safe-stop functions such as SS1, SLS and SMS in the family documentation. STO removes torque capability but is not a substitute for the full risk assessment your machine standard requires.
