Operation principle is：After switch connection power supply, if magnetictrip, thermal trip are no different paradoxical reaction, normal operation is switched.Work as line
When short circuit or heavy overload electric current occur for road, short circuit current is more than instantaneous trip setting current value, and magnetictrip generates enough
Big suction, armature is attracted, and pull rod makes moving contact be detached with Electricity conductive plaster under the drive of armature, cuts off the power.Work as circuit
When general overload occurs, though overload current cannot be such that magnetictrip acts, static contact can be made to generate certain heat, promoted
Sheet metal on thermal trip, which is heated, to be bent upwards to detach with static contact, is cut off the power.
The breaker is disadvantageous in that static contact is only provided with one group, therefore breaker is only applicable to connection one kind
The electric appliance of load.However, existing household electrical appliance in the family are more and more, load is also increasing, therefore to breaker load
It is required that also continue to increase, but the load of breaker is nor simply greatly with regard to suitable, if being easy for greatly very much causing family's line
Still breaker plays the role of trip protection to excess load not yet on road, if too small be easy for causing breaker ceaselessly
Tripping, makes troubles to life.
