Siemens 3VA9447-0FK31 Door-Mounted Rotary Operator for 3VA53/54

The Siemens 3VA9447-0FK31 is a door-mounted rotary operator for SENTRON 3VA molded case circuit breakers. It transfers the breaker handle to the front of the enclosure door, so the breaker can be switched on and off without opening the panel.

The operator meets NEMA enclosure types 1, 3R, 12 and 4/4X in the standard version, and includes a door interlock together with a door opening position. The interlock prevents the door being opened while the breaker is closed, and the defined opening position allows authorised access when required.

It is an accessory for the 3VA53/54 and 3VA63/64 breaker frames. Supplied as a single piece with a net weight of 0.6885 kg in a 180 x 140 x 450 mm carton, it suits switchgear and control panels where safe front-of-door operation is required.
