    • What replaces a 3RU1126-4AB0

    There are two choices when replacing the 3RU1126-4AB0: keep the existing contactor and purchase a new overload with a separate mount bracket or replace the entire unit (contactor and overload) with the new Siemens Sirius series.  Comparison of both options are listed below.

     3RU2126-4AB0 + bracket   3RU2126-4AB0 + New 3RT contactor

     Pros:

    • Most inexpensive means to replace
      obsolete overload

    Cons:

    • Need sufficient panel space (either
      DIN Rail or screw down) to mount
      overload bracket
    • Must now wire overload to contactor
      since will not direct mount
    		  

     Pros:

    • Saves space
    • Ease on installation (no need to run
      new wires from overload to contactor)
    • Newest generation of Siemens line and
      will be around for many years to come

    Cons:

    • Most expensive replacement option
      since contactor also needs to be replaced
