Saftey that every home needs, make sure to buy the correct one per the information on your panel.

It seems to be a good surge protector, although fortunately I haven't had to put it to the test yet. But it didn't quite fit into my panel. Maybe it's an older panel (early '70s?) but the divider between phases was too wide on my panel for the slot in the surge protector. I had to carve out the slot in the surge protector to fit into the panel. Otherwise it would have been an easy installation.

I think this is a new or redesigned product as they work in the older panels. My home was built in 1988 and I had previously purchased Square D whole house surge protectors for inside the panels, but the connections would not work with my panels. There was no indication that they would not work except for in the big product catalog. When I found these I verified there was no such warning in the catalog for this part number. Installed the first one today. Now ready to order for the second panel. My installation took about 20 minutes. Don't forget to de-energize the panel before you work on it.

Power strips with surge protection is not enough, this surge breaker will protect more items before the power strip can. Good fro warranty on items and insurance

Doesn’t fit over bar, doesn’t fully engage bus bars. Got it finagled in, but it’s not correct for a brand new Square D QOC panel. Pretty frustrating. Broke case so can’t send back, but it’s not the right thing.

This is a very clever product. Eliminate all the power bars in your house and concerns about damage to appliances and other expensive electronics. Fairly easy to install with the correct electrical know-how. Have since purchased one for our strata neighbor and encouraged friends to get one as well
