Description of AC Contactors

WTC1 serious ac contactors are suitable for using in circuit of frequency 50/60Hz, rated insulation voltage up to 1000v, rated operation current 9-95A under AC-3 duty. It is mainly used for making/breaking electric circuits at a long distance for frequent starting/stopping&controlling AC motors. It is used in combination with a thermal relay to compose of a magnatic starter. It is in conformity with the standards of IEC60947.4.1 and GB14048.4.
