3TF 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 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 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 panle in the Ie22A contactors. in the le32A contacotors. there are moulded arc-chute with arc-isolated panel. because all contacts are made of high nonfusibility and against corrosion silver alloy. All series products can be mounted by screws, le32A contactor also by installation rail.
