QF220A Ground Fault Circuit Interrupter, 20 Amp, 2 Pole, 120V, 10,000 Aic,

Works great for a variable speed pentair pump. My pool was installed with a generic gfci breaker that faulted every month or so which was particularly concerning during freeze protection. I read this Siemens breaker is the same as the pentair branded one. It was easy to install and I haven’t had one fault since installed many months ago. Highly recommend if you are having issues with a pentair pump and a generic breaker that keeps flipping.

I don't know a whole lot about electric, but after a way-too-close lightning strike, the outside outlets wouldn't re-set the GFI. I took a picture of the old one, got all the info I could and ordered this one, an exact duplicate of the ruined one. Killed the power (so it wouldn't kill me!), carefully removed the old one, keeping track of which wire went where, installed the new one and voila! Everything was working again and I probably saved $100+ on an electrician service call. (This is the point where I have to insist that you use qualified electricians for ALL your critical electric work, right? Right. Carry on.)

My dishwasher and garbage disposer are each on a different hot 20 amp circuit but share a neutral. So, I could put a gfci outlet to replace each of the existing outlets, and that would protect each outlet. But, both outlets are under the sink and behind the tangle of pipes and drains, and I'm an old man. A gfci breaker for each circuit would require a neutral to be shared and that's not going to work. So I used this guy; the 20 Amp, 2 Pole Ground Fault Circuit Interrupter breaker. Two hots and one neutral. Took me 10 minutes to install it, works perfectly. It's huge, but fit okay in my 40 year-old panel. It's the only way I could protect the circuits from the panel. Expensive but well worth it. The breaker brand must match what's in your panel already. For me, I had old ITE stuff that is replaced by Siemens brand. Good luck.

This allowed my VFD pool pump to work. However, keep in mind that this thing barely fit in my GE Load Center Panel. I had to move all of the common and ground wires from the spots next to this breaker and take out all of the screws from that section of the grounding/neutral bar to make space to click the breaker in the panel. Any electrician would be able to figure it out, but I don't know if it will fit in all typical panels. I am satisfied since I was able to make it work. The original GE GFCI breaker kept tripping from the VFD pool pump, so installing this one fixed the problem.

My prior pool breaker tripped once a week. All the suggestions on the web said the breakers is never the problem. I replaced everything else, and nothing helped. This replacement breaker no longer trips. So breakers can fail.

If you have a Pentair variable speed pool pump and it randomly trips, chances are it is the current GFCI double 20 amp breaker you have installed in your pool pump panel. Since my pool was about 6 months old I've had this problem. It was sporadic. Would happen once and then not again for a few days. It was driving me crazy. We'd be on vacation and I'd look on my cameras to find my pump off. The breaker would trip at the most random times. I told my pool builder and of course they didn't want to do anything about it. So I got my trusty clamp style volt meter and made sure my pump wasn't drawing too many amps, of course it was fine. Only pulling 8 amps on high speed, so I knew that wasn't it. I read on a forum that they recommended this breaker for Pentair pool pumps. I found the one Pentair has and it is identical to this one, except it is $60 more. Since installing, I haven't had the tripped breaker problem again.

Same as what I was replacing. Good price.

It worked out perfect for us. No complaints.
