Automated Mains Disconnect for High-Power ATV Drives
The VW3AP0276 is an automated mains disconnect accessory for the Altivar Process ATV600 and ATV900 drive families, sized for drive systems rated 710 and 800 kW. It serves as the line-side switching element that isolates the drive from the supply under load or fault conditions — effectively a motor-rated disconnect that can be integrated into the drive system's control logic rather than requiring a separate manual handle.
Sourcing Constraint: Enclosure Required
A critical procurement constraint: the VW3AP0276 cannot be ordered alone. It is only available in combination with a standard enclosure. This means the disconnect ships as part of a pre-assembled drive system package — not as a standalone component for field retrofits. If your BOM calls for this order code as a separate line item, verify that the enclosure is already specified on the drive system order; otherwise the distributor cannot fulfil the line.
Deployment Context: Drive System Integration
Designed for the compact drive system architecture of the ATV600 and ATV900 series, the VW3AP0276 mounts inside the standard enclosure that houses the drive itself. It handles the automated break-before-make sequence that protects the drive DC bus capacitors from inrush on power-up and provides a controlled disconnect on power-down. For a panel builder or system integrator, this means the disconnect is already wired into the drive's control circuit — no separate contactor or manual switch needs to be added upstream.
The VW3AP0276 has a lifecycle stage of mature and an active product status, indicating steady-state production. No end-of-life notification exists.
