3TF 3 Pole Ac Contactor 24V Coil Flame Retardant Electrically Controlled
A contactor is an electrically-controlled switch used for switching an electrical power circuit. A contactor is typically controlled by a circuit, which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch.
3ST(3TF) AC Contactors, Magnetic 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 motors or
system. They form electromagnetic starters with suitable thermal
overload or phase-failure. They are made 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 between the contact support and core, three are no arcisolated panle in the Ie≤22A contactors. in the le≥32A contacotors. there are moulded arc-chute with arc-isolated panel. because all contacts are made of high nonfusibility and against corrosion silver alloy. All series products can be mounted by screws, le≤32A contactor also by installation rail.
