AI Customer ServiceTo close a circuit breaker, the "CLOSE" control element is actuated either electrically through the closing magnet or mechanically through a push button arrangement. This enables the spring-stored energy mechanism to release its energy, which rotates the common shaft through the linkage system.
The Indoor VCB operating mechanism consists of a closing spring, an energy storage system, an overcurrent release, and a switching system. It can be divided into two types: manual and electric operation. The manual operating mechanism has the functions of manual energy storage, manual opening, closing, and over-current protection.
A circuit breaker equipped with a current transformer, when the current flowing through the main circuit of the circuit breaker exceeds the rated value of the transformer, a 5A current is output through the secondary side of the transformer, the internal overcurrent release of the drive mechanism is driven, and the circuit breaker is opened.
