Detailed Product Description

      3TF series AC Contactors are suitable in electrical system with AC50

/60Hz,rated operational voltage up to 660V.In AC-3 usage,rated operat-

ional voltage up to380V,rated operational current up to 630A to make or

break remote motors or system.They can form electromagnetic starters

with suitable thermal overload relays 3UA series to protect system and

motors against overload or phase-failure.They are made according to

IEC947-2 ,Bs5424 & VDE0660.The contactor is a straight motion mec-

hanism having double-breaking contacts.The auxiliary contacts are ar-

ranged 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 Ie≤22A contactors.In the In≥32A contactors,there are moulded arc-

chute with arc-isolated panel.Because all contacts are made of high non-

fusibility and against corrosion silver alloy All series products can be mo-

unted by screws,Ie≤32A contactor also by installation rail.
