The Square D Homeline QO2175SB Surgebreaker is a secondary layer of protection against electrical surges that can cause outages and short circuits on your home. When a surge causes the voltage to exceed its normal value, the surge arrester stops the voltage and diverts the remaining temporary current until the surge passes.

The Surgebreaker secondary surge protector is a plug-in unit that installs as easily as a circuit breaker in a two-pole space. The QO2175SB surge arrestor works with QO style load centers, combination service entrance devices and NQ panelboards. An LED indicator shows operational status of the unit.

I live in an area that has frequent power outages and we attribute some appliance issues and damage because of this. So hopefully this surgebreaker will help protect against electrical spikes. But of course I won't know until some more happen. The product is very easy to install and the price is reasonable.

I had installed this product about 4 years ago thinking all electronics in the house would be protected. Recently had a major lightning strike. The only electronic items that survived were the ones that a point-of-use surge protector (surge strips). I now replacing the unit I had installed since it was burned up during the strike. I am also installing point-of-use strips on ALL electronic devices. I think this unit helped, but needs to be part of an overall plan.

My home had this component installed when I purchased it. When doing some electrical upgrades, I called Square D to obtain technical information about this product. Basically, it is designed to work as part of a whole-house surge protection system. It handles large voltage/current spikes on a single phase 240V main. It does not successfully handle very short (or very high frequency) spikes, and so the general recommendation is to install a service-end surge protector (receptacle or power strip) for sensitive devices. I had done so for circuits in my house that run sensitive such as computers, A/V equipment, etc., and after 3.5 years, have never had any device in my home fail due to power spikes.
