3VA9677-0FK21 SIEMENS

The 3VA9677-0FK21 is a door-mounted rotary operator designed for seamless integration with Siemens 3VA55, 3VA65, and 3VA66 molded case circuit breakers (MCCBs). This operator provides a user-friendly interface for controlling the circuit breaker from outside the electrical panel. Compliant with IEC standards, it ensures reliable performance and safety.

A key feature is the integrated door interlocking accessory, which prevents the panel door from being opened while the circuit breaker is in the 'ON' position, enhancing safety during maintenance and operation. This interlocking mechanism minimizes the risk of accidental contact with live components. The rotary operator facilitates easy and intuitive switching of the circuit breaker. Its robust construction ensures longevity and dependable operation in diverse conditions. The 3VA9677-0FK21 enhances both the functionality and safety of electrical installations using compatible Siemens MCCBs.
