2. After closing the circuit breaker, if the closing electric signal is not removed in time, the internal
anti tripping controller of the circuit breaker will cut off the closing circuit to prevent multiple reclosing.
3. When the handcart type circuit breaker fails to reach the test position or working position, the
handcart interlocking board 19 shall buckle the closing board and cut off the closing circuit to prevent the
circuit breaker from entering the load area in the closing state.
4. After the handcart type circuit breaker is closed in the working position or test position, the trolley
will not be able to move if the roller presses the pushing mechanism, so as to prevent pulling out or
pushing the load area in the closing state.
5. If electrical closing locking is selected, manual closing operation is prevented when the secondary
control power supply is not connected.
