Helping in contactor

  1. Jun 27, 2009 #1
    Hi everybody

    I am new here but I hope that you help me.

    I need wiring diagram for 3-phase contactor with two switches one for start (give the contactor the signal) and the other for stop.

    when the electricity went off , the contactor should stop working

    it's too simple not complicated


    Best Regards
    Ahmed Hassan

    We don't have any idea because we don't know which contactor you have. What makes you think all contactors have the same terminal numbers?

    I know that's every contactor has it's only terminal numbers but.....

    If there is 21 and 22 number in contactor , what is the situation for?

    No (Normally Open)
    Nc (normally Closed)

    I found that the connection terminal for (21 and 22) normally Closed and the terminals (13 and 14) Normally Open if the contactor not work

    Just a sugestion, but perhaps in the future you could at least make a token effort to find the information yourself before stating a thread here. Obviously the information was available to you; this could have been finished a week ago.
