Specifications
3TF series AC contactor are suitable in electrical system with AC 50/60Hz, rated operational voltage up to 660V. In AC-3 usage, rated operational voltage up to 380V, rated operational current up to 630A to make or break remote motors or system. They form electromagnetic starters with suitable thermal overload or phase-failure. They are made according to IEC 60947, BS 5424 & VDE 0660.
The contactor is a straight motion mechanism having double breaking contacts. The auxiliary contacts are arranged NO.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.
