      Transition Timeline

      As timelines are finalized, dates will be further clarified below.

      November 2016: Introduction of PowerPact B
      June 2017: Obsolescence of F-frame molded case circuit breakers and switches announced
      Q4 2018:
      PowerPact B enclosures available
      I-Line F-frame circuit breakers and switches no longer available for purchase
      Q2 2019: Unit mount F-frame circuit breakers and switches no longer available for purchase

      Finding a Replacement
      PowerPact B 15-125A Molded Case Circuit Breakers and switches are the designated replacement for F-frame applications. PowerPact B features increased capacity, a smaller size in unit mount, same size to ease retrofit in I-Line, and a flexible range of field-installable accessories, auxiliaries and operators.



      Tools and Resources:

      Breaker Substitution

      Replacing a F-Frame Unit Mount/Enclosure Installation
      Your current F-frame unit mount/enclosure application may require minor adjustments to accommodate PowerPact B due to the smaller physical size of the new circuit breaker.
      Two adapter plates are available:  

      • HJKADAPT: Screw mounted substitution of F-frame circuit breakers
      • LV426995: F-frame to PowerPact B-frame 9421 Rotary Handle Conversion Plate Kit

        NOTE:         This plate conversion also requires a new 9421LB7 operating mechanism and one new shaft kit: 9421LS8 or 9421LS13.

      Replacing an F-frame I-Line Installation
      No adaption is required if you have an I-Line application. F-frame and PowerPact B I-Line circuit breakers are the same size to ease the retrofit process.
