What is the difference between the CHFN and CHFP Breakers?

With the addition on the new CH Plug-On Neutral loadcenter designs, the catalog numbering system has changed to reflect the added PON breakers. Plug-On Neutral breaker designs are applicable to both Arc-Fault and Ground-Fault styles. The two designs will be available as follows:

  • CHFP- The CHFP catalog numbers will be for the CH Plug-On Neutral breakers. These will work in all CH Plug-On Neutral loadcenter designs.
  • CHFN- The CHFN catalog numbers are the more traditional design, with a pigtail neutral connection. These will work in all legacy CH loadcenter designs, as well as the new PON loadcenter designs.
