GE Q-Line THQL 15-Amp 1-Pole Combination Arc Fault Circuit Breaker - 71223240
This GE Q-Line 15 Amp 1 in. single pole Arc Fault combination circuit breaker detects Arc Fault in both parallel and series wiring. The circuit breaker has a tin-plated copper stab that creates permanent and corrosion-resistant connection. The calibration screw is cemented to prevent shifting and provides a stable connection. The attached screw creates a stable calibration for optimum performance. The breaker case is made of heat-resistant thermoset for stability and structural integrity.

What our Experts Think
-
Advanced fire-safety protection (15A AFCI)
Detects dangerous arc faults in wiring and shuts off power to help reduce the risk of electrical fires in residential branch circuits.
-
Combination arc fault detection (series + parallel)
Provides broader protection by identifying both types of arc faults that can occur from damaged wires or loose connections.
-
Designed for GE Q-Line load centers
Compatible with GE/ABB residential panels using THQL breakers, ensuring proper fit and reliable operation.
-
1-pole, 120V branch circuit use
Ideal for standard home circuits such as bedrooms, living rooms, and general lighting/outlets.
-
Built-in test function & trip indication
Includes a test button and center-trip position to quickly identify when protection has activated.
-
Durable, heat-resistant construction
Engineered with a thermoset case and copper stab connection for long-term stability and corrosion resistance.
-
Code-compliant residential safety upgrade
Meets modern electrical safety standards where AFCI protection is required in many home installations.
Q&A
Q: What is this breaker used for?
A: It provides combination Arc Fault Circuit Interrupter (AFCI) protection for 120V branch circuits, helping prevent electrical fires caused by arc faults in home wiring.
Q: What type of protection does it offer?
A: It detects both series and parallel arc faults and automatically shuts off power when a dangerous condition is detected.
Q: Where is it typically installed?
A: In residential GE Q-Line load centers for circuits like bedrooms, living rooms, and other AFCI-required areas.
Q: Is it compatible with GE panels?
A: Yes, it is designed specifically for GE Q-Line / ABB ReliaHome residential load centers.
Q: Does it include a test function?
A: Yes, it has a built-in test button to verify arc fault protection is working properly.
Q: What does “combination AFCI” mean?
A: It protects against both series arcs (loose/broken connections) and parallel arcs (hot-to-neutral faults) for broader safety coverage.
Q: What is the main benefit?
A: It helps reduce the risk of electrical fires while meeting modern electrical code requirements for AFCI protection in homes.
Maintenance Tips
-
Test monthly: Press the built-in test button to confirm arc-fault protection is working properly.
-
Reset correctly after trip: Move handle fully OFF, then ON to restore protection after a trip event.
-
Avoid circuit overloads: Keep load within 15A rating to prevent nuisance tripping and overheating.
-
Inspect panel condition: Ensure breaker is firmly seated, dry, and free from dust or corrosion.
-
Watch for frequent trips: Repeated tripping may indicate wiring issues, loose connections, or arc faults requiring electrician inspection.
-
Check test response: If test button fails or behaves inconsistently, replace breaker immediately.
-
Keep neutral connections secure: Loose neutrals can affect AFCI sensing and performance.
-
Do not bypass AFCI protection: Always replace with a compatible GE Q-Line breaker when needed for safety compliance.
