The VW3AP0503 is an enclosure heater kit for Altivar Process ATV600 and ATV900 compact drive systems. It ships as a complete assembly: one enclosure heater, one thermostat, and one 6 A circuit-breaker. This is not a loose heater element — it is a kitted sub-assembly ready for panel integration.
This kit is sized for drive systems rated 560 to 800 kW. It mounts inside the standard enclosure that ships with those drive frames. The thermostat and 6 A breaker provide overcurrent and temperature control for the heater circuit.
Ordering constraint
The VW3AP0503 cannot be ordered alone — it is only available in combination with a standard enclosure. If you are sourcing this as a spare or replacement, confirm the enclosure is on the same purchase order. No holes in the kit, but the enclosure must travel with it.
