ESC1 AC Contactor

Application

      ESC1 AC contactor is 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 IEC60947, B85424 & VDE 0660.
     The contactor is a straight motion mechanism having double-breaking contacts. The auxiliary contacts are arranged 2N0,2NC at most. It is employed the flexible locking connection between the contact support and core, there are no arc-isolated panel in the le≤22A contactors. In the ≥32A conductors. There are moulded arc-chute with arc-isolated panel. All can be mounted by screws, le≤32A conductor also
by installation rail.
