Combination Arc Fault Circuit Interrupter (AFCI)

Electrical fires in homes break out more then 67,000 times each year in the U.S. alone. Many result from arc faults. Arc faults are unintended electrical arcs that may ignite combustible materials in the home. Four types of arc faults may occur: line-to-line, line-to-ground, line-to-neutral, or a series arc fault, which is arcing over a gap within a single wire.


  • ABB is one of the few companies to offer AFCI in a 1 inch standard breaker package freeing up valuable wire space.
  • Fulfills 2008 National Electric Code (and later) requirements for all dwelling units.

Arc faults arise from a number of situations, including:

  • Damaged wires
  • Receptacle leakage
  • Neutral leads pinched to grounded metal box
  • Worn electrical insulation
  • Loose electrical connections
  • Shorted wires
  • Wires or cords in contact with vibrating metal
  • Overheated or stressed electrical cords and wires
  • Misapplied/damaged appliances





Branch/Feeder AFCI

A Branch/Feeder AFCI has the ability to detect and neutralize a parallel arc fault, which is the unintentional flow of electricity between two separate wires. There are three types of parallel arc faults: line-to-line, line-to-ground, and line-to-neutral. The Branch/Feeder AFCI is permitted by the 1999-2005 NEC® Code.


Combination AFCI

GE's Combination AFCI delivers 5 kinds of protection:

  1. Parallel protection − Just like its Branch/Feeder counterpart, Combination AFCI can detect and neutralize parallel arc faults
  2. Series Protection − A series arc fault is the unintended flow of electricity over a gap within a single wire. These arc faults were not detectable until advanced technology allowed the development of the Combination AFCI breaker.
  3. Ground protection − Arcing between a single conductor and a ground line
  4. Overload protection
  5. Short circuit protection
