It allows users to remotely control the circuit breaker's on/off status without direct access to the internal components. The rotary handle design provides a user-friendly interface for operating the circuit breaker. This door-coupling mechanism ensures a secure and reliable connection between the circuit breaker and the enclosure door. It is crucial for applications where the circuit breaker needs to be operated from a distance or when it is housed in a protective enclosure. The robust construction of the mechanism ensures durability and long-term performance in demanding industrial environments. Its standardized design guarantees compatibility and ease of installation with the specified 3VA27 circuit breaker model. By enabling external operation, this accessory contributes to improved safety and operational efficiency in electrical systems.
