Whole House Surge Protective Devices (SPDs) are designed to deliver surge suppression that addresses the entire home. Surges can enter your home’s electrical system externally (e.g. lightning or utility surges) or most often, can be generated within the home by other equipment and appliances. Point-of-use plug strips with surge suppression are good secondary suppressors for equipment that can be plugged-in. However, a primary Surge Protective Device (SPD), such as a Square D brand Whole House Surgebreaker Plus installed at the load center, reduces large surges to manageable levels. Even more, it helps protect the thousands of dollars in equipment that can't be plugged into a plug strip (e.g. washer, dryer, HVAC, stove, dishwasher, refrigerator, lighting). Square D brand Whole House SPDs combine AC suppression with coaxial cable and telephone suppression in one product. These additional modules help protect systems and devices throughout the home from surges that come through telephone/DSL and cable/satellite video and data wires. The SDSB1175C is NEMA 1 rated for indoor applications. For indoor/outdoor applications, consider the SDSB1175R. It is the same product but in an enclosure that provides a NEMA 3R rating for indoor/outdoor applications.

Rated 4.7 out of 5 by 10 reviewers.
Rated 4.0 out of 5.0 by Good features for a decent price Took off one star because the clearances inside are too tight. Very difficult to plug in coax from the bottom knockouts (like the instructions say to do). If you put a cable clamp in the side knockout, the threads on it will push the entire mounting plate to the other side. If Square D made the housing just a little bigger (1/4 inch on each side and 1 inch on bottom) it would be perfect. Other than that it is a great value and buys peace of mind for protecting your electronics and appliances. July 10, 2012
Rated 5.0 out of 5.0 by Highest KA rating I am by trade an electrical contractor and always use the best equipment I can especially when it is my own home. I have all Square D QO equipment in my main and sub panels. This equipment has the highest ampere rating at 80,000 amps in this price range so it would provide the highest protection again lightining strikes as well as surges from the power or cable lines caused by surges through the utility companies lines for whatever reason. The other cheaper models offer less so they may not be enough for a lighting strike close to home or worse, a direct strike. Also the modules are replaceable. I do not have the need for the telephone module because frankly those surges don't concern me but it came with the equipment Also i'm not sure I can run the fiber optic line through it. The cable line though could carry quite a bit of voltage in the event of a surge or strike though. All in all, you get what you pay for and just one of these would easily pay for itself rather than calling a repairman to fix an appliance or have to throw away a dvd or tv. Also the model number matches the model number from the supplier so this is not an inferior brand made just for Home Depot. I installed a separate 220 volt 20 amp breaker for it so that I can turn it off if I had to run an emergency generator to back feed my electrical panel. Generators are BAD for electronics so you want to resist using them when connected to a generator and they can also and will also damage the surge protector. January 29, 2013
Rated 5.0 out of 5.0 by GOOD PRODUCT FOR A FAIR PRICE I had the previous version of this installed and it mediated a power surge thus necessitating its replacement. Unfortunately, the new versions physical dimensions are incompatible with the old versions metal cabinet and the whole unit must be replaced rather than just the AC module. So if your version did not come with the HEPD80 AC module prepare yourself to open the wall and replace the entire surge protector unit. August 6, 2013
Rated 5.0 out of 5.0 by Usefulness Remains To Be Proven Ratings predicated upon this device, installed professionally by my electrician, protecting the electronics in my home from a power surge. For now, it is only an expensive metal box with two green glowing lights that is mounted to the left of my Square-D breaker panel. August 27, 2014
Rated 5.0 out of 5.0 by Whole House Surge Protector After doing my homework this product proved superior in load shunting capability (80,000 VA). For the sake of the warranty I had a licensed electrician install unit (required), He was impressed with the Square "D" name, as it is a leader in the industry. Also note that the $75,000 insurance coverage only covers the deductible, if that is the lesser of the loss. This seems to be standard policy for the surge protection industry. When weighing the purchase warranty against other products note if they are only covering "motor driven appliances". Square "D" covers all equipment, including computers, TVs, etc. Note also that it was not recommended by my cable supplier to run the their line through the cable surge protector because there would be a loss in signal. My cable provider supplies me with phone, cable TV and internet (Comcast),all on the same line. Since I now enjoy 50mbs download speed I was reluctant to compromise my signal. They said if the house is properly grounded I should be protected. We'll see about that. November 4, 2014
