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. The form electromagnetic starters with suitable thermal over load or phase-failure. The are mode according to IEC947.BS5424 & VDE0660.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 le≥32A contactors, there are moulded arc-chute with arcisolated panel, because all contacts are made of high nonfusibility and against corrosion silveralloy. All series products can be mounted by screws, le≤32A contactor also by installation rail.
