The VW3AP2101 is a motor heater accessory for Schneider Electric's Altivar Process ATV600 and ATV900 drive systems. It delivers up to 200 W of heating at 230 V AC to keep the drive enclosure above the dew point in cold or humid environments.
What it does and how it fits
The VW3AP2101 is a heating accessory composed of a circuit-breaker, a contactor, and a terminal block, all pre-assembled. It mounts inside the drive enclosure and is wired to the 230 V AC supply. The 200 W rating is sized to prevent condensation in the cabinet when the drive is idle — typical for outdoor or unheated electrical rooms.
