S3TF series AC contactors are suitable in electrical system withAC 50/60 HZ, rated operational voltage up to 660V. In AC-3 usage.rated operational voltage up to 380V, rated operational current upto 630A to make or break remote motors or system, They can formelectromagnetic starters with suitable thermal overload relays 3 UAseries to protect system and motors against overload orphase-failure. They are made according to IEC947-2,BS5424 &VDE0660.

The contactor is a straight motion mechanism having double-breakingcontacts/The auxiliary contacts are arranged 2NO.2NC at most. It isemployed the flexible locking connection between the contactsupport and core. There are no arc-isolated panel in the ie< 22Acontactors. Inthe in >32A contactors.there are moulded arc-chutewith arc-isolated panel. Because all contactors are made of highnon-fusibility and against corrosion silver alloy. All seriesproducts can be mounted by screws.ie < 32A contactor also byinstallation rail.
