The VW3A9905 is a ready-assembled IP54 base plate from Schneider Electric, designed for the ATV61 and ATV71 drive ranges. Its job is to increase the number of cable connections available on the drive — a practical add-on when you've run out of gland entries in the standard enclosure.
Cable gland configuration
The plate ships with a specific gland layout: one metal ISO40 gland for the motor cable, one plastic ISO12 and one plastic ISO20 for control cables or options, one special plastic ISO32 for the network cable, three plastic ISO40 glands for control cables or options, and four plastic ISO16 glands for control cables or options. That's a total of eleven gland positions, sized to handle the full cable set for a multi-cable drive installation.
Lifecycle reality — obsolete
Schneider has classified the VW3A9905 as obsolete. No direct successor order code is listed by the manufacturer. For a drive that's still in service — and plenty of ATV61 and ATV71 installations are still running — this base plate is a critical spare: one in the cabinet means no scramble when a gland plate gets damaged or a cable addition is needed.
