3TF AC Contactor

3TF series AC contactors are suitable in electrical system with AC 50/60Hz,rated operating voltage up to 660V.In AC-3 usage, rated operating voltage up to 380V,rated operating currnet up to 630A to remotely make or break motors or system.They form electromagnetic startes with suitable thermal overload relays 3UA5 series to protect system and motors against overload or phase-failure. They are made according to IEC947,BS 5424 & VDE 0660.The contactor is a straight motion mechanism having double breaking contacts. The auxiliary contacts are arranged 2 NO,2 NC at most. It is employ the flexible locking connection between the contact support and core. There are no arc-isolated panel in the le¡Ü22A contactors. However in the le¡Ü32A Contactors, there are isolated panel .Main contacts are made of high non-fusibility and against corrosion silver alloy. All series products can be mounted by scews, le¡Ü32A contactor also by nstallation rail.
