AC contactor is in the state of sorption

The contact is closed, in order to control high current loads purpose of the work. According to the working principle of AC contactor, when the AC contactor in the state  Voltage stabilizer , the AC current through the AC contactor coil will consume some energy. For example, a CJ20-250A AC contactor, according to one day work 8h, 1 years 300 days of work, the annual  circuit breakers consumption for the 156kW · h. As our country is running a large, medium-capacity AC contactor large number of  power transformers  energy consumption up very alarming. Therefore, AC contactor saving technology with a very large economic and social benefits. AC contactor is to make energy-saving technologies in the DC contactor mode operation.
