Square D - QO120DFC QO 20 Amp Single-Pole Dual Function (CAFCI and GFCI) Circuit Breaker

Having installed over 1000 Load Centers in my working for a living years , I found Square D products are the most dependable . I suggest them to my customers when they ask for my opinion . The QO line costs more , but you get what you pay for !

Installed easily - product delivered quickly

About 40 years ago I put in a 40 circuit 200 amp breaker box. As time went on I upgraded my breakers to the (then new) electrical code that required GFI breakers in areas that were close to water, were in a garage, or were on the exterior of the house. Eventually interest in using arc fault protection developed since their use reduces the likelihood of having an electrical fire. The GFI was great for reducing the risk of electrocution due to placing yourself into "hot wire to ground" circuit. However, the GFI had limited ability to stop arc faults. Now the combination GFI + Arc fault devices are becoming reasonably priced. The Square D - QO120DFC is an excellent choice for those who are safety oriented. (update: After 6 moths of use all of these breakers are working properly -- Several of them tripped when we had a two day power failure that put significant voltage surges and drops on our electrical service. They worked well when we turned on our back-up generator.)

Since it’s hard to tell these days, thought others would appreciate knowing at least these 20 A dual function QO breakers I got appear to be the real thing in the same sealed factory packaging as I have purchased retail from the usual big box stores ( but a much better price! Thank you. )

Shipping was fast . Used breaker in garage

All as promised

Great replacement breaker. I used this one for the dishwasher

Square D is well known amongst the electricians as the best breakers available. I requested this when I wired my building and bought this breaker to offer GFCI protection in my metal building workshop. I purchased several of these and they so far work great and no bogus trips as of yet and using for woodworking tool 20 amp 110 volt outlets. I liked this better than putting in gfci outlets daisy chained together. Easy to install and tested these and work great. Will buy more as needed.

Es de buena calidad pero no me funcionó para el tablero eléctrico que tenía, tengo que cambiar por un Modelo: QOX204 de scuare D.

Same product as local but cheaper and meets code

Amazing price compared to local dealers, and with Prime I can't believe how fast they arrived. Ordered at 21:00, arrived the next day before 17:00. Square D QO (thought not bolt in breakers) are great and with arc/ground fault protection, I love these breakers.

works has describe

Works good wish I could say same for the 2 pole mwbc version , that’s not made anymore. Highly suggest conversion to single pole if possible to avoid compatibility issues with appliances, leds, etc.
