The Siemens 3VA9467-0FK51 is a door-mounted rotary operating mechanism (handle accessory) used with SENTRON 3VA1 / 3VA2 MCCBs (typically 400A–630A frame range). It allows the circuit breaker to be operated externally from the panel door, providing safe ON/OFF control without opening the electrical enclosure.
This accessory is mainly used in industrial switchboards, MCCs, PCCs, and heavy power distribution systems where safe and visible isolation is required.
