Siemens Boltshield FSPD036 Level 2 Whole House Surge Protection Device Rated for 36,000 Amps, 120/240V

so far so good,works pretty well,

OK, only got few hours ago and installed inside another breaker panel for my A/C unit. Extra panel had room for one more double pole circuit breaker ! Other choice was put on outdoor condenser or indoor blower unit where it would be in sight; not covered inside a breaker panel. All panels are recessed in walls. Have another brand on another service for about a decade now and no issues, so have faith this panel service with a fraction of power draw will have issues. (same incoming service line) Guess once a year I may pull cover off to check ; just 4 screws. Would be nice for an indoor unit built onto a double pole breaker as one unit, but size restrictions would make it difficult to fit universally. Believe just a double pole circuit breaker spacing unit could be made. Then no wiring, just snap in place. Seimens is a great brand.

Power surge got my new refrigerator motherboard. Luckily I figured it out reducing my bottom line. Immediately purchased this to protect my equipment ! It has a light letting you know it's working properly.

Can't beat this surge protector for the price of a whole house SP. Easy install, Siemens quality!

Easy installation. No way to assess effectiveness.

Very well designed unit (internally). Works well.
