APPLICATION:
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 motos or system.The form electromagnetic starters with suitable thermal over load or phase-failure.The are mode 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 be-tween the contact support and core,three are no arcisolated panle in the le≥32A contacotors,there are moulded arc-chute with arcisolated panel,because all contacts are made of high nonfusibility and against corrosion silveralloy.All series products can be mounted by screws,le≤32A contactor also by installation rail.
