What the kit does
The VW3A95118 is a flush-mounting kit for Altivar Process ATV630 and ATV930 variable speed drives rated up to 690V AC. It lets you mount the drive's power section outside the enclosure while keeping the control section inside — useful when the drive's heat dissipation would overload a sealed cabinet. The kit includes a fan support, a metal frame cut to the right size for the drive rating, corner pieces, fixing accessories, seals, and a user manual. The seals and frame make the installation dust- and damp-proof, matching the enclosure's environmental rating.
The flush-mount arrangement separates the power section from the control electronics, which helps with thermal management in dust- and damp-proof enclosures where airflow is limited.
