CJX8(B) AC contactor (ZNFO Traditional series)

CJX8(B)series AC contactor is mainly used in the electric power circuits with the frequency of AC 50Hz or 60Hz,the voltage of up to 690Vand the  rated  current  of up  to  370A  for  connecting  and  breaking  circuits  remotely  or  frequently  controlling  AC  motors  and  providing  the under- voltage protection.It  often  works with  the  JR29  series  thermal  relay  to  form  the  electromagnetic  starter  to  provide  overload  and  open-phase protection.It can also be provided with the mechanical interlocking to form a reversible contactor.

    CJX8 (B) series AC contactor

    Structural features of the product

    AC contactors of CJX8-30 and below adopt the “normal installation structure", that is, the contact system is at the front, and this system is at the back (near the installation surface: CiX8-37 and above adopt the "inverted structure", that is. the magnetic system is at the front and the main contact system is at the back.
    The moving contact is of bridge structure.For CIX8-105 and above, the main static contact can be separated from the main wiring, so it is not necessary to disassemble the main conductor when replacing the contact.For CIX8-9-25, there are four pairs of contacts (three pairs of main contacts and one pair of auxiliary contacts or four pars of main contacts).For CiX8-30 and above, the moving contact bracket is provided with three moving contacts, and the number of main contacts cannot be increased.
    CIX8-9~CJX8-25 AC contactor adopts enclosed natural arc extinguishing, C]X8-30-45 adopts ferromagnetic sheet for arc extinguishingCJX8-65 and above adopt ferromagnetic grid for arc extinguishing. All products adopt arc-resistant plastic arc chambers.
    CJX8-9~CJX8-30 AC contactor can be quickly installed on the 35mm installation rail conforming to IEC standards.This series of contactors can be provided with different types of auxiliary contacts to increase the convenience of use (see table).
