The 3VA9467-0FK23: This is a Siemens door mounted rotary operator from the 3VA9 accessory family, designed specifically for 3VA1 and 3VA2 molded case circuit breakers in the 400 A and 630 A frame sizes. It provides external ON/OFF switching with a door interlock and includes a 24V DC lighting kit for status indication.
Fit and Use
Mounts on the enclosure door, connecting to the breaker via a rotary shaft. The door interlock prevents opening the door when the breaker is ON—standard safety measure for switchboard compartments. The 24V DC LED lighting kit illuminates the handle position, useful in low-light panel environments. Rated IP65 from the operator side, so the front of the panel stays sealed against dust and hose-directed water. Interfaces with 3VA1 and 3VA2 breakers up to 630 A confirmed by the product family designation.
