The VW3AE0504 is an enclosure heater from Schneider Electric, designed as an accessory for the Altivar 71 Plus-LH and Altivar 61 Plus-LH floor-standing drive cabinets. It mounts inside the enclosure to maintain a minimum internal temperature, preventing condensation on sensitive drive electronics during off-hours or in cold environments.
The heater is intended for Altvar floor-standing enclosures with separate air flows or the compact version. It is not a general-purpose cabinet heater; fit is specific to the Altivar 71 Plus-LH and 61 Plus-LH cabinet architecture. Verify the enclosure model and heater mounting location before specifying.
