12, second connecting rod 42 must be latched and handle 41 is in poised state.When breaker occur short circuit, overvoltage, overload, it is under-voltage situations such as
When its in tripping driving device driving trigger member 31 and such as Fig. 5 of tripping 11 is turned clockwise, tripping 11 release to lock 12
Motion limit, i.e. tripping 11 12 is separated with lock, so that such as Fig. 5 of lock 12 are around the rotate counterclockwise of the 5th rotating shaft 75, together
When second connecting rod 42 active force of the handle 41 away from open position is disappeared, handle 41 turns to open position.At the same time, due to
Such as Fig. 5 of lock 12 on rotating turret 54 makes rotating turret 54 turn clockwise around the rotate counterclockwise of the 5th rotating shaft 75, therefore rotary shaft
71 can cause dynamic iron core away from static iron core, breaker open operation such as Fig. 5 rotate counterclockwises, the synchronous rotary of stake body 62.
The circuit breaker operation mechanism of the present embodiment also includes power saving features, and the power saving features can be in 41 turns of the handle
Power off the coil 22 when moving closing position.
Because handle 41 is turned to after closing position, coil 22 is powered off, now, if acting on hand without direct external force
Tripping driving device driving trigger member 31 in handle 41 or breaker causes tripping 11 to be separated with lock 12, then handle 41 is still protected
Hold in closing position, accordingly, the dynamic iron core 21 keeps contacting with static iron core 23, and the energy-conservation for thus achieving breaker subtracts
