It can be used to distribute electric energy, not frequently start asynchronous motor, protect power supply circuit and motor, when they are in serious overload or short circuit and under-voltage, it can automatically cut off circuit, its function is equivalent to the combination of fuse switch and over-under-heating relay, etc. and after breaking fault current it generally does not need to change parts, so that it has been widely used.
The traditional small-sized breaker and switch opening and closing actions need to be completed by manual operation. With the development of smart power grids, small-sized circuit breakers and switch products capable of reliably realizing automatic switching on and off are urgently needed. Therefore, an electric operation device capable of driving opening and closing operations of a small-sized circuit breaker and a switch, which is used in cooperation with the small-sized circuit breaker and the switch, has appeared in the market. By sending instructions to the electric operating device, the miniature circuit breaker and the switch can be driven to automatically open and close without manual operation, thereby effectively saving manpower and material resources and being increasingly widely applied. On one hand, if the driving motor rotates to enable the handle of the circuit breaker to be in the middle position, on the other hand, the common circuit breaker in the existing market fails, at the moment, the circuit breaker is not closed in place, the handle and the gear transmission mechanism are in an engaged state, and the handle cannot be pulled to the closing position through manual operation to supply power for a user; on the other hand, the trip piece stroke of the conventional circuit breaker is not reliable enough and the trip piece is easy to impact to cause the damage of the trip piece.

An operation space is reserved between the transmission mechanism and the handle mechanism, and the operation space is enough for the handle mechanism to perform manual opening or closing operation. The switching-on driving device and the circuit breaker using the same are simple in structure, low in manufacturing cost, small in size and suitable for small-sized circuit breakers. And provides manual closing/opening functions while providing automatic closing. However, an operation space is reserved between the handle mechanism and the gear connecting rod mechanism of the switching-on driving device, so that remote switching-off cannot be realized.
