Contactors

Place of Origin:	Shanghai

This AC contactor is suitable in electrical systems with AC 50/60Hz with
rated operational voltage up to 660V. It is also used in AC-3 usage,
rated operational voltage up to 380V, rated operational current up to 630A
to make or break remote motors or system. It 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 IEC and BS standards. 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. There are no arc-isolated
panel in the ?ü22A contactors. In the ?ü32A contactors, there are molded

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 mounted by screws, ?ü32A contactor also by installation rail.
