AMCF3 intelligent permanent magnet anti-shaking electric AC contactor is improved on the basis of AMC3 intelligent permanent-magnetic

contractor, with a circuit logical analysis & time release module added, thus to conduct safe and effective circuit logical analysis and control. Thiskind of special intelligent contactor will achieve no time delay during opening & re-closure under normal working condition, and will initiate anti-interference electricity status when the interference electricity is triggered."Interference electricity" - during the operation of electrical power system, due to the lightning strike, short circuit to the earth, re-closure/backupautomatic switching, grid fault within/beyond the enterprise, and grid fault caused by the starting of large-scale equipment, a phenomenon is incurred with instantaneous sharp voltage fluctuation or short power supply interruption & recovery, which is called as "interference electricity".Although the interference electricity only lasts for several seconds, it is catastrophic for the enterprise which allows no trip-out shutdown of electric motors in the technological processes of many devices during continuous production. It may cause economic losses of RMB thousandsor hundreds of thousands in less severe cases, and it can even lead to fire, explosion and hazard against personal safety in more severe cases, which is truly catastrophic to enterprise.

Scope of application

AMCF3 intelligent permanent magnet anti-shaking electric AC contactor is mainly used for AC 50Hz, 60Hz, rated working voltage to rated voltage to 690V; in the power system, it is responsible for turning on and off the circuit and can hold the contactor without tripping when the continuous production line suffers transient voltage loss and power loss  (commonly known as electricity interference) in the power supply system because of lightning strike and short circuit. The operation of turning on and off is the same with conventional contactor. When the blackout time exceeds the limit time, the contactor will trip and has avoided electricity interference and kept a continuous production without

stopping the machine.
