What this kit is and what it fits
The VW3A9802 is a mounting kit from Schneider Electric's Altivar 71 range, designed for installing the drive inside a dust and damp proof enclosure. The kit composition includes one heatsink, one thermal liner, one manual, and hinged mechanical adaptors. It is intended for enclosures with a thickness from 1.5 to 3 mm, in stainless or paint-finished smooth steel with heat-treated epoxy paintwork of fine or medium texture.
Schneider Electric has marked the VW3A9802 as Obsolete. If you are designing a new panel around an Altivar 71, factor in that the drive itself is also a mature product; the mounting kit's obsolescence reinforces the case for a platform migration.
