The Siemens QA120AFC is a plug-in combination arc-fault circuit breaker (CAFCI) that provides comprehensive electrical protection for residential and commercial applications. This breaker combines arc-fault and ground-fault protection, detecting dangerous electrical arcing conditions that standard circuit breakers cannot identify. It is required by the 2005 NEC (National Electrical Code) on bedroom power and lighting circuits, making it an essential upgrade for modern electrical safety.

Arc faults can occur due to worn electrical insulation, damaged wiring, misapplied or damaged appliances, and loose electrical connections—all potential fire hazards. The QA120AFC protects downstream branch circuit wiring, cord sets, and power supply cords against these risks while also providing traditional overload and short-circuit protection. Its intelligent trip-detection system displays LEDs for up to 30 days after a trip event, indicating whether an arc fault or arc fault to ground occurred, helping electricians diagnose problems quickly.

Features and Benefits

  • Combination CAFCI Type: Complies with requirements for both branch/feeder and outlet circuit CAFCIs, providing arc fault, overload and short circuit protection in one unit.
  • NEC Compliant: Meets 2005 NEC requirements for bedroom power and lighting circuits, ensuring your electrical system is up to code.
  • LED Diagnostic Indicators: Two LEDs activate for 5 seconds each time the breaker is switched on, displaying up to 30 days of trip history to identify the type of fault that occurred.
  • Comprehensive Protection: Guards against worn insulation, damaged wiring, faulty appliances, and loose connections that pose fire risks.
  • Plug-In Design: Standard plug-in construction fits existing electrical panels without extensive modifications.
