• Provides Ground Fault and Arc Fault circuit protection

• LED blinks on trip to show the last know trip condition

• Automatic and continuous self-testing feature

• GE DFCI has important features for assisting you or your electrician in troubleshooting a trip, should the DFCI trip, the yellow LED will blink to indicate the last known trip condition

• Unit's last known trip condition via LED indicators appear for 5 seconds each time the DFCI is turned on for up to 30 days

• Unit’s last known trip condition can be cleared by performing a series of functions provided in the instructions

• DFCI has a Self-Test feature that meets a June 2015 requirement from UL on all Ground Fault circuit breakers

• The warranty is one (1) year from first use or eighteen (18) months from delivery, whichever occurs first

What our Experts Think

• Dual Protection in One Breaker
  Combines AFCI (arc-fault) + GFCI (ground-fault) protection, helping reduce risk of electrical fires and shock from a single device.
• Advanced Residential Safety Upgrade
  Designed to meet modern code requirements for kitchens, laundry areas, bedrooms, and living spaces where enhanced protection is required.
• Fast Fault Detection Technology
  Continuously monitors circuit conditions and trips instantly when dangerous arc faults or leakage currents are detected, improving safety response time.
• Self-Test Reliability System
  Built-in automatic self-testing ensures ongoing protection integrity, reducing the risk of unnoticed failure over time.
• Diagnostic LED Indicator
  LED status light helps identify whether a trip was caused by arc fault or ground fault, simplifying troubleshooting and reset decisions.
• Space-Saving 1-Pole Design
  Fits standard GE Q-Line load centers while providing two protection systems in one breaker slot, helping maximize panel space.
• Professional Installation Use
  Intended for GE/ABB compatible residential panels, typically installed by licensed electricians for code-compliant wiring setups.

Q&A

Q: What does this circuit breaker do?
A: It provides dual protection by combining AFCI (arc-fault protection) and GFCI (ground-fault protection) in one device to reduce fire and shock risks.

Q: What is AFCI protection for?
A: It detects dangerous electrical arcs caused by damaged wiring or loose connections and helps prevent electrical fires.

Q: What is GFCI protection for?
A: It detects ground faults (current leakage) and quickly shuts off power to prevent electric shock.

Q: Where is this breaker commonly used?
A: Typically required in residential circuits like bedrooms, kitchens, living areas, laundry rooms, and other code-required locations.

Q: Is it compatible with GE panels?
A: Yes, it is designed for GE Q-Line / PowerMark load centers and compatible ABB/GE panels.

Q: Does it have safety or testing features?
A: Yes, it includes a self-test function and LED indicators that help identify trip conditions and improve troubleshooting.

Q: What wire sizes does it support?
A: It typically accepts #14–8 AWG copper and #12–8 AWG aluminum conductors.

Q: Is it certified for safety standards?
A: Yes, it is UL listed, NEMA approved, and ANSI certified for residential electrical safety use.

Q: Why choose a dual-function AFCI/GFCI breaker?
A: It saves panel space and provides two critical safety protections in one device, meeting modern electrical code requirements while improving overall home safety.

Maintenance Tips

• Test monthly: Press the TEST button to verify both AFCI (arc fault) and GFCI (ground fault) protection are working properly.
• Reset safely after trips: If it trips, fully switch it OFF then ON to reset—don’t force it halfway.
• Keep panel dry and clean: Prevent moisture, dust, and insects inside the load center to avoid false trips or corrosion.
• Inspect wiring annually: Have a licensed electrician check for loose neutrals, burnt terminals, or overheating signs.
• Avoid overloading the circuit: Stay within 15-amp limit to prevent nuisance tripping and heat stress.
• Check LED indicators: Use trip lights to identify whether the issue is AFCI (arc) or GFCI (ground fault).
• Do not mix incompatible panels: Ensure it is installed only in compatible GE/ABB load centers to maintain safety certification.
• Schedule periodic professional inspection: Dual-function breakers are safety-critical and benefit from yearly electrical review.
