The VW3A9902 is a ready-assembled IP54 base plate from Schneider Electric, designed for ATV61 and ATV71 drives to increase the number of cable connections. It is now classified as obsolete.
What the cable gland count means for fit
The plate provides a dedicated cable gland layout: one metal ISO25 for the motor cable, one plastic ISO12 and one plastic ISO25 for control or option cables, a special plastic ISO32 for the network cable, plus three plastic ISO20 and four plastic ISO16 glands for additional control or option cables. This pre-drilled arrangement saves panel-build time and ensures the IP54 seal is maintained without field-drilling.
Schneider has marked the VW3A9902 as obsolete.
