Product Description
Application
3TF contactor is suitable for using in the circuit up to the Rated voltage 660V AC 50Hz, Rated current up to 95A, for making, breaking, frequently starting & controlling the AC motor. Combined with the auxiliary contact block, air delayer & machine interlocking device etc, it becomes the delay contactor, mechanical interlocking contactor, star delta starter. With the thermal relay, it is combined into the electromagnetic starter. The contactor is produced according to IEC 159-1, VDE0660 & BS5452.
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 arc isolated panel in the le≤ 22A contactors. In the In≥ 32A contactors. There are moulded arc-chute with arc-isolated panel. Because all contacts are made of high confusability and against corrosion silver alloy. All series products can be mounted by screws, le≤ 32A contactor also by installation rail.
