■Key lock
Circuit breaker unlocking: When the notch on the key corresponds to the red dot on the lock, the key
can be inserted into the lock. When the key rotates clockwise to the rightmost
position, it can be unlocked. At this time, the key cannot be directly pulled out, and
the circuit breaker can be closed.
Circuit breaker locking: Press the opening button of the circuit breaker, and then turn the key
counterclockwise to the leftmost position to remove the key. At this time, the
circuit breaker cannot be closed.
Note 1:
The following list of power supply modes is for reference only. The installation and interlock
can be performed according to the needs of the actual power supply system on site, or the
manufacturer can be consulted for negotiation.
One lock and one key: One circuit breaker is equipped with a lock and a key. In the locked state, the
circuit breaker is not allowed to be closed.
