Siemens 3VA9157-0FK61 Door Mounted Rotary Operator IP65

The Siemens 3VA9157-0FK61 is a door-coupling rotary operating mechanism for compatible SENTRON 3VA10/11 molded case circuit breakers. It lets the breaker be operated from the panel door, instead of directly at the device, which is useful in enclosed switchboards and industrial panels. This version is a standard, rigid, door-mounted rotary operator without tolerance compensation, with door interlock and IP65 protection on the operated front. It is the right fit when the buyer needs a genuine Siemens accessory for safer, cleaner external breaker operation.
