GK3TF series ACcontactor are suitable for electrical system with AC 50/60Hz,ratedoperational voltage up to 660V. In ac-3 usage, rated operationalvoltage up to 380V,rated operational current up to 630 A to connector disconnect remote motors or system. It can be organized intothermal magnetic starter and applied to thermal overload relay. 3TFseries are used to protect system and motors from overload or phasefailure. They are made according to IEC947, BS5424 &VDE0660.
