Siemens QSA2020SPD Whole House Surge Protection with Two 20-Amp Circuit Breakers for Use Only on Siemens Panels & QF250A Breaker Ground Fault Circuit Interrupter, 50 Amp, 2 Pole, 240 Volt, 10,000 AIC

This product is very easy to install and still give you two circuits to connect

Overall a good surge suppressor that is exceptionally easy to install, although I strongly recommend against ANY Homeowner working in their electrical panel. It's a good way to get killed, or injured if you are not a qualified electrician. Having said that, you should be aware that this surge suppressor will not protect from a lightning strike that enters the house on a low-voltage coax, or data line. Think of the path it takes. If the surge comes in through the service cables into your main electrical panel, it will have to go through a whole-house surge suppressor before it goes through the branch circuit breakers, but that is an unlikely scenario. "Whole-house" is a misnomer, because as I mentioned, this surge suppressor, or any other brand that mounts inside, or attaches to the main electrical panel, will not protect from a lightning strike that enters through a low-voltage line. Not only that, most whole-house surge suppressors are not going to offer a lot of protection from a lightning strike because they don't usually enter the house through the main electrical panel. The factory-recommended installation is at the top 2 spaces below your main breaker on either side. (This also holds true for other brands powered by a separate 2-pole breaker.) Also know most of the surge suppressor companies do not guarantee "connected" loads, which means virtually any plugged-in, or hard-wired load (appliance, TV, other electronics, etc.). You also need to be aware that all the manufacturers of "whole-house" surge suppressors recommend "layering" surge strips throughout your house in conjunction with a whole-house suppressor. This gives an added layer of surge protection. Leviton has a pretty good one that mounts outside the panel and is powered by a separate 2-pole breaker. It comes with a seemingly good warranty, although I have never had to exercise it. This suppressor is definitely a more difficult install than the Siemens, though. The Siemens whole-house surge suppressor we are talking about did do its job on one of my customer's house that had a compromised neutral from a car hitting a power pole in the neighborhood. Both green lights were out and the unit was fried due to high voltage spikes on each incoming 120 volt leg. The unit had a strong burnt odor to it and it was replaced. Most people do not realize that voltage spikes are most commonly caused by "compromised neutrals", not lightning strikes. These are usually caused on the power companies side of the equation, but you will never get any recourse from them. Trust me. My comments are from personal experience and I am a long-time electrical contractor.

I was searching for an external device when I happened upon this combp unit. Absolutely hit the mark.

The warranty only promises that this will protect your house wiring from damage due to surges, NOT anything you've plugged in. However, I bought it because it was the easiest way to ensure that every outlet in the house had at least some protection, whether I used a separate surge protecting power strip or not; it will reduce the risk to other devices even if they don't promise that.Installation is straightforward for your electrician; if you have a load center that accepts QSA breakers, it clips in just like any other double breaker, putting one "mini breaker" on each phase so you don't lose useful space in the box. It does require one space on the neutral bus inside the box along with the wires you attach to feed the loads.Note that the surge protection appears to be downstream from those internal breakers; protection is inactive when those are turned off. I presume this is so that if one of the MOVs fails short-circuit while absorbing a heavy surge, it will blow the breaker and protect the rest of the house. But it does mean that if you are using the output of those breakers (rather than just plugging it in for the protection) it's better to use that for circuits which are almost always on; if there's a circuit you turn off sometimes, it would be better to connect it to a standard breaker rather than this.

A recent winter storm with power fluctuations took out a surge suppressor and other electronics in the house. This was enough for me to look for a good easy solution for my whole house. The surge breaker installed easy in the top right slots and I transferred over two circuits that were on existing 20 A breakers. Took no more than 20 minutes.

I've wanted to add surge protection to my load center for quite some time. But my load center is extremely full. This device allows you to replace two adjacent 20 amp circuits and still achieve the surge protection. I suspect I won't know if it works unless it fails.

Replaces the 2 circuit beakers closest to where the power enters your panel . If you know how to replace breakers, this is a simple DIY install. Shutting main power off is recommended.

Easy to install in my Siemens panel. Like some other reviewers mentioned, the front face label surrounding the LEDs was a bit crooked on mine. This is because the shape of the breakers behind is tapered which doesn’t leave much surface for the label to stick to. This doesn’t affect the functionality of the breakers at all, but it is a bit annoying. I trimmed the label a bit to get it to line up better.

Installation is easy. Using the product to prevent current surges to protect sensitive equipment.

Easy to install if you know what your doing. Time will tell if it works. Unfortunately there is know way to know if it working. Two green light and your good to go.:)

I just purchased the Sieman's 20 AMP Circuit Breaker and Surge Protective Device and has it installed in our breaker panel. The installation is easy if you know what you are doing. I had an electrician do the installation in order to not void our insurance coverage.

I bought this unit because it fits right in to my Siemens 100A power panel. It is not a separate unit like some others that has to be mounted outside of the breaker area. Some others also require a circuit breaker to be purchased anyway. Delivery took a few weeks in these pandemic times. It may have been shipped from the US and I live in Canada, which may explain some of the delay. After it was installed and power was restored to the panel, I put the 2 breakers on, but I could not see the green indicator LEDs. I had to move the plastic cover over a bit so the LEDs could shine through the holes in that cover. Only time will tell if it trips during a surge and protects against overvoltage damage.
