3TF Series AC contactor
Application
3TF series AC contact are suitable in electrical system with AC 50/60Hz, rated operational voltage up to 660V. In AC-3 usage, rated operrational voltage up to 380V, rated operrational voltage up to 630A to make or break remote motors or syatem. They form electromagnetic starters with suitable thermal overload or phase-failure. They are made according to IEC 60947, BS 5424 & VDE 0660.
The contactor is a straight motion mechanism having double breaking contacts. The auxiliary contacts are arranged NO.2NC at most, it is employed the flexible locking connection between the contact support and core, there are no arcisolaed panel in the le≤22A contactor. In the le≥32A contactors. There is no moulded arc-chute with arc-isolated panel, because all contacts are made of high confusability and against corrosion siliver alloy. All series products can be mounted by screw, le≤32A contactor also by installaion rail.
