  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.

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.
