I have a LC240PC Murray breaker box (probably around year 1995).

I found what I believe is the breaker I'm looking for here: https://www.homedepot.com/p/Murray-20-Amp-AFCI-GFCI-Dual-Function-Circuit-Breaker-MP120DFP/205488021

But that one is discontinued and it says the replacement is this: https://www.homedepot.com/p/Siemens-20-Amp-1-Pole-Dual-Function-CAFCI-GFCI-Plug-On-Neutral-Circuit-Breaker-Q120DFNP/312276201

However, the correct one (first link) has a pigtail to plug into the neutral bar, and the replacement one (second link) does not (it says it is for "Plug On load centers". I believe that my box is not the Plug-On style, so I would need the pigtail.

Is there a different replacement breaker (Dual function CAFCI+GFCI)that is still an active product that has the pigtail?

    You're correct that you need the pigtail. Home Depot's site is wrong, which happens all the time. The right breaker is definitely made, and a more competent shop will help you find it. Other than that, shopping/procurement questions are off-topic here. Commented May 20, 2021 at 16:23

You need the pigtail neutral version of what you're looking at

Your problem is that Home Depot sent you off to the Plug-on Neutral (N suffix) version of the Q120DF, which isn't compatible with older panels. Instead, you need the plain Q120DF(P), which has a neutral pigtail on it and is compatible with your panel.


PON (Plug On Neutral) panels are a relatively new development. Given the date of your panel there's virtually no chance its a PON panel. You'll need to find a breaker with a pigtail.
