AC Contactor (3TF46)

Product Description

3TF series AC contractor 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 IEC60947, BS5424 & VDE0660.3TF AC contactor, 3TF AC contactors.

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, three are no arc isolated panel in the le¡Ü22A contactors, In the In¡Ý32A contactors, there are mounded arc chute with arc-isolated panel. Because all contacts are made of high no fusibility and against corrosion silver alloy All series products can be mounted by screws, le¡Ü32A contactor also by installation rail. 3TF AC contactor, 3TF AC contactors.
