They can form electromagnetic starts with suitable thermal overload relays 3UA series to protect system and motors against overload or phase-failure. They are made according to IEC60974-4.
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 is 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 contactors are made of high non-fusibility and against corrosion silver alloy. All series products can be mounted by screws, Ie≤32A contactor can be mounted by installation rail.
