Contactor to start and stop

Is a double coil structure, the power state, the control module is in the storage state, the start and stop of the contactor contacts as electri cenergy meter, when the "shake" occurs down to the contactor so that the voltage below the sustain voltage, control module initiated work to release the stored energy in the form of air circuit breaker contacts continue pull. When the supply voltage is restored, the control module and transferred to the storage state. Since the control module uses a Circuit breaker conversion components, making electrical contact resistance Akira volume and mounting structure to maintain the original features, in addition to the work that it does not rely on auxiliary power and auxiliary mechanical devices, so small size and high reliability.
