Part identity and constraints
The VW3AP1114 is a braking unit option for the Altivar Process ATV900 drive series, sized for 630 kW systems in the size 2c enclosure format. This braking unit carries an IP54 degree of protection with a plinth, meaning it is sealed against dust ingress and water splashes — suitable for installation in washdown or dusty environments where a standard open-chassis braking resistor would not survive. A critical sourcing constraint: the VW3AP1114 cannot be ordered alone; it is only available in combination with a standard enclosure from the ATV900 drive system.
Because this braking unit is tied to a specific enclosure combination, procurement should confirm the matching drive system enclosure part number at the time of quoting to avoid a mismatch on the BOM line.
Integration note
Mounts as part of the ATV900 drive system enclosure stack — the plinth provides the IP54 seal at the cable entry point, so verify gland sizes match the incoming power and braking resistor cables before commissioning.
