It ships as a complete assembly: one enclosure heating element, one thermostat, and one 6 A circuit-breaker. ## Sourcing constraint — cannot order standalone This part carries a specific condition of use: it cannot be ordered alone. It is only available in combination with a standard enclosure for the drive system. If you are sourcing for a panel build or a replacement, the enclosure order must include this heater — it is not a separate line item you can add later without the base enclosure part number. ## What it does in the drive system The heater prevents condensation inside the drive enclosure when the drive is powered down or in a humid environment. The thermostat cycles the heating element to maintain internal temperature above the dew point. The 6 A circuit-breaker provides local overcurrent protection for the heating circuit. For a 110-315kW drive cabinet, this is a standard fit — without it, moisture can accumulate on power terminals and control boards, leading to tracking failures or corrosion over time.","metaTitle":"VW3AP0551 Enclosure Heater, ATV600/ATV900, 110-315kW","metaDescription":"Schneider VW3AP0551 enclosure heater for Altivar Process ATV600/ATV900 drive systems 110-315kW.
