 3 Pole solid state AC Magnetic Contactor for phase-failure / overload Protection

 


 
Application
 
 
SHF series AC contactors are suitable in electrical system with AC 50/60Hz, rated operational voltage up to 380V, rated operational current up to 630A to make or break temote motors or system. They can form electronmagnetic starters with suitable thermal overload relays 3UA series to protect system and motors against 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, 2NX 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 In≥32A contactors, there are moulded 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, le≤32A contactor also by installation rail.
