The ATV630D22N4 is a 22 kW normal-duty / 18.5 kW heavy-duty VFD from the Altivar Process ATV600 series, designed for asynchronous and synchronous motor control in process applications like pumps, fans, and conveyors. Rated supply voltage is 380-480 V, 50/60 Hz, with a continuous output current of 46.3 A at 4 kHz carrier in normal duty, derating to 39.2 A in heavy duty — the heavy-duty figure governs motor starting and overload cycles. Line current at 480 V normal duty is 34.4 A — this is the figure to use for upstream breaker and contactor sizing, not the 46.3 A output rating. The integrated EMC filter covers 50 m for C2 (restricted distribution) and 150 m for C3 (industrial) environments per IEC 61800-3, eliminating the need for an external filter in most panel builds.
Safety and compliance — STO and standards stack
CE marking is present, confirming conformity with applicable EU directives for placement on the European market.
Field integration — mounting, cooling, and environment
Wall-mount design with IP21 protection (IEC 60529) and UL Type 1 enclosure — suitable for indoor panel installation where drip protection is sufficient, but not for washdown or outdoor use. Forced convection cooling moves 215 m³/h of air, with a noise level of 59.5 dB — audible in a quiet control room but typical for a drive of this power class. Operating altitude derating starts above 1000 m at 1 % per 100 m, and the drive must be mounted vertically within ±10 degrees — both points matter for installation in elevated plant areas or non-standard orientations. Vibration resistance is 1.5 mm peak-to-peak at 2-13 Hz and 1 g at 13-200 Hz per IEC 60068-2-6, with shock resistance of 15 g for 11 ms — tough enough for most industrial machinery without additional isolation.
Sourcing and lifecycle — active production, quoted to order
No stock-holding claim — quoted per RFQ. The standard version means no conformal coating or severe-environment options — if the installation sees condensation or conductive dust, consider the coated variant of the same drive family.
