The VW3A5217 is a sinus filter for Altivar Process variable speed drives, rated 45 A continuous with a maximum permissible voltage of 690 V AC. It cleans up the PWM waveform from the drive output to reduce motor winding stress and bearing currents — a common fix for long cable runs or older motors that don't like the sharp edges of a standard IGBT output. Switching frequency is fixed at 2 kHz, and the filter passes output frequencies up to 70 Hz. That covers most 4-pole induction motor applications up to base speed. The 60 s overload capability of 1.5 x nominal current handles the occasional jog or acceleration transient without oversizing.
That means the BOM line stays stable for new builds and spares alike. No last-time-buy clock ticking on this one.
Mounting is open-chassis (IP00), so it goes inside a panel or enclosure — not a standalone box. Terminal-block electrical connection, no special tooling needed. Thermal losses run 360 W at rated load with a 115 °C hot-spot temperature; plan the enclosure ventilation or derating accordingly. Operating ambient is -10 to 45 °C, storage from -40 to 65 °C. Above 1000 m altitude, derate 1 % per 100 m. Pollution degree 2 per EN 50178 means it's fine for a typical industrial control room or MCC — not for condensing or conductive-dust environments without a sealed cabinet. Shock rated at 15 gn for 11 ms per IEC 60068-2-27, vibration at 1 gn from 13 to 200 Hz with 1.5 mm peak-to-peak below 13 Hz. That's robust enough for most fixed-mount industrial applications; if it's going on a mobile platform or near a large reciprocating compressor, check the actual spectrum against the curve.
Listed to UL 508 — the industrial control equipment standard. That covers the safety and construction requirements for North American panel builds. Humidity tolerance is 0 to 95 % RH non-condensing.
