Application
S-N series AC contactors are suitable for AC 50Hz or 60Hz, rated voltage up to 660V, mainly used as putting through long distance, breaking circuit and frequently starting to control AC motor. It can also be used for counter-connection breaking of squirrel-cage motor in the case of reducing working current.
