The VW3AP1115 is a braking unit option for the Altivar Process ATV900 drive family, sized for 800 kW systems in the size 2c frame. It carries IP54 protection with a plinth, meaning it is sealed against dust ingress and water spray — suitable for installation in environments where washdown or airborne particulates are present, though the unit itself must be integrated into a standard enclosure. This is not a standalone component. The condition of use states it cannot be ordered alone and is only possible in combination with a standard enclosure. Plan the enclosure integration at the same time as the braking unit order — the VW3AP1115 arrives as part of a matched drive system, not a loose accessory.
Because it is an enclosure-integrated option, availability is tied to the full drive system build.
Integration note for the drive system
Rated for the Altivar Process ATV900 platform, this braking unit is dimensioned for the size 2c cabinet. The IP54 plinth provides a sealed base entry for cabling. Verify the enclosure cutout matches the ATV900 system layout before committing the panel design. As an electrical accessory in the compact drive system category, its function is to dissipate regenerative energy from decelerating motor loads — common on conveyors, hoists, or centrifuges where the load overhauls the motor. The braking resistor (not included) must be sized for the duty cycle of the application.
