3TF34 3TF35 Series AC contactor
Application
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 660A to make or break remote motors or system. They form electromagnetic starter with suitable thermal overload or phase-failure. They are made according to IEC947,BS5424 and 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 supply and core, three are no arc-isolated panel in the le≤22A contactors. in the le≥32A contactors.three are moulded arc-chute with arc-isolated panel. because all contactors are made of high non-fusibility and against corrosion silver alloy. All series products can be mounted by screws, le≤32A contactor also by installation rail.
