The Schneider Electric VW3GB661316F1 is a 16 A RFI filter from the R-FP U41/U54 series, designed for line-side harmonic and EMC suppression on variable-speed drives. The part is marked obsolete by the manufacturer.
Schneider classifies the VW3GB661316F1 as obsolete.
What the 16 A Rating Means
The 16 A current rating sizes the filter for the line input of a drive drawing up to that continuous current. In practice, this covers small to mid-range Altivar drives on 400 V three-phase supplies. The filter attenuates conducted emissions in the 150 kHz to 30 MHz range to meet EMC directive limits — a common requirement for CE-marked installations.
Where It Mounts
The R-FP U41/U54 form factor is a panel-mount enclosure with cable glands for line and load connections. It installs between the mains supply and the drive input, typically on a backplate or DIN-rail adapter bracket. Keep the filter close to the drive line entry — long input cables radiate before the filter.
