## Overview

The Siemens QA120AFC is a 20-Amp single pole Combination AFCI breaker designed to detect both parallel and series arcing faults, enhancing electrical safety. Featuring LED trip indicators for easy fault diagnosis and an improved wiring design with extra bend space and aligned lugs, it ensures quick, hassle-free installation. Ideal for modern residential circuits, this plug-on mount breaker combines robust performance with smart safety features.

## Description

The Combination Type AFCI differs from the Branch/Feeder AFCI in its ability to detect series arcing faults. The Branch/Feeder AFCI can only detect line-to-neutral and line-to-ground arcing faults. Combination AFCIs provide protection against the high-energy parallel (line-to-neutral and line-to-ground) arcing and low-energy series arcing. "Combination" does NOT mean an AFCI + GFCI. Combination = parallel + series arcing. Combination AFCIs protect downstream branch circuit wiring, cord sets and power supply cords. Siemens Combination Type AFCI trip indicators provide a valuable analysis tool to help electricians pinpoint the type of trip. These indicators are in the form of LEDs that appear near the handle of the breaker. The LED indications will appear for 5 seconds each time the AFCI is turned "ON" up to 30 days after the last trip.

## Questions & Answers

**Q: What is the difference between the qa115afc and the qa115afcp?**
A: The QA115AFCP comes in a plastic package, the QA115AFC comes in a cardboard box. Other than the packaging they are identical.

**Q: Is qa120afc interchangeable with mpa120afc?**
A: Q is the code for a Siemens breaker.  MP is the code for a Murray breaker.  The same company makes both breakers.  Some people use them interchangeably with no problem.  However, manufacturer wants you to use Siemens breakers with Siemens panels. Also, electrical inspector might give you a failing grade because you are not following manufacturer rules. Siemens brand is usually a higher price.

**Q: I have a ge type tql can i use this to replace my breaker?**
A: First of all, you said it, "General Electric".  Most commonly, BR, QP, TQL would attach to the Panel, But the Manufacture usually specifies the Type of breakers allowed onto their Panels. On your existing panel that this TQL is coming off of, please look at the Manufacture's requirements.  If, your existing panel is a, GE, I'm 100% sure you are not allowed to use this Siemens QA120AFC. Unfortunately, I would not recommend that you do so.

**Q: What is Difference between q120afc and qa120afc?**
A: The Q120AFC is an older version of standard arc-fault breaker. The Q120AFC was replaced ty the Combination Type AFCI breakers which is current design part# QA120AFC.

### ⭐⭐⭐⭐⭐ My old AFCI breaker kept tripping - This works as advertised
*by C***G on December 19, 2023*

My old AFCI breaker kept tripping. My options were to get an electrician to find out why it suddenly started tripping or replace the breaker with a new one. Replacing it was much cheaper than getting an electrician, and the new breaker is not tripping. It works great.
