Product Description

3TF series AC contactor is used for making and breaking, and for frequent starting and controlling the motor.3TF series AC contactor mainly used for making/breaking electric.CJX1/3TF series AC contactors are suitable for frequency 50/60Hz,rated insulation voltage up to1000V,rated operation current 9~475A under AC-3 duty.It is mainly used for making/breakingelectric circuit at a long distance & for frequent starting/stopping & with thermal relay to com-pose a magnetic motor starter.The product conforms to IEC60947-4-1 stardand.The contactor is a straight motion mechanism having double breaking contacts. The auxiliary contacts are arranged 2NO.2NC at most, it is employed the flexible locking connection between the contact support and core, three are no arcisolated panel in the Ie≤22A contactor. In the In≥32A contactors. Three are moulded arc-chute with arc-isolated panel, because all contacts are made of high cnonfusibility and against corrosion silver alloy. All series products can be mounted by screw, Ie≤32A contactor also by installation rail.
