The Schneider Electric VW3AP0501 is an enclosure heater designed for Altivar Process ATV600 and ATV900 drive systems in the 110 to 160 kW power range. It ships as a complete assembly: one enclosure heating element, one thermostat, and one 6 A circuit-breaker.
Sourcing and integration note
The VW3AP0501 cannot be ordered alone — it is only available in combination with a standard enclosure. That means it arrives pre-fitted as part of the drive system package, not as a loose accessory you wire in later. If you are sourcing this for a BOM line, confirm the enclosure part number is included on the same purchase order. The heater assembly is intended for compact drive systems, so it mounts inside the drive enclosure to maintain a minimum internal temperature and prevent condensation. The built-in thermostat and 6 A circuit-breaker provide local overcurrent and temperature control without external panel components.
Lifecycle and supply posture
This is not a phase-out or end-of-life line — it is a current-production accessory that Schneider continues to support for the ATV600 and ATV900 series. Because it is a captive accessory (tied to the enclosure), availability follows the drive system's production schedule.
