APPLICATION:
3TF series AC contactors 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 operatonal currnet up to 630A to make or break remote motors
or system. They form electromagnetic starters with suitable thermal overload
relays 3UA5 series to protect system and motors against overload or
phase-failure. They are made according to IEC947, BS5425 & VDE0660. The
contactor is a straight motion mechanism having double-breaking contacts. The
auxiliary contacts are arranged 2 NO. 2 NC at most. It is employed the flexible
locking connection between the contact support and core, There are no
arc-isolated panel inthe le<22A contactors. In the In >32A contactors,
there are moulded arc-chute with arc-Bolated panel. Beause all contacts are
made of high non-fusibility and against corrosion silver alloy. All series
products can be mounted by screws,le<32A contactor also by installation
rail.
