Application
3TF series AC contactors 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 are made according to IEC60947-4.
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.
There are no arc-isolated panel in the le≤22A contactors. In the In≥32A contactors, there are moulded are-chute with arc-isolated panel.
Because all contacts are made of high non-fusibility and against corrosion sivler alloy. All series products can be mounted by screws, le 32A contactor also by installation rail.
