C7N AC Contactor
Applications
C7N series AC contactor are suitable for frequency 50/60Hz, rated insulation voltage up to 1000V, rated operation current 9-330A under AC-3 duty. It is mainly used for making/breaking electric circuits at a long distance & for frequent starting/stopping & controling AC motors. It is used in combination with thermal relay to compose a magnetic motor starter.
Rated operating voltage & rated insulation voltage of the contactor see table 1.
