The VW3AE0645 is a sinus filter from the Schneider Altivar 71 Plus range, designed as a protection accessory for Altivar floor-standing enclosures with separate air flows or the compact version.
Schneider lists the VW3AE0645 as obsolete.
What This Filter Does
A sinus filter sits between the drive output and the motor, smoothing the PWM waveform to reduce motor heating, bearing currents, and acoustic noise. On an Altivar 71 Plus floor-standing cabinet, this filter is a bolt-on protection accessory — not a standalone component — so verify the mechanical fit and electrical rating against your specific drive frame before ordering.
