3TF series of AC contactors are suitable in electrical system with AC 50Hz or 60Hz, with rated operational voltage up to 660Vac, and with rated operational voltage up to 380V for AC3 load, and with rated operational current from 9A up to 630A for the purpose of making or breaking remote motors or system. They from 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 arc isolated panel in the le ≤ 22A contactors, in the le ≤ 32A contactors, there are moulded are-chute with arc-isolated panel. Because all contacts 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.
