Good quality as expected from Siemens

Would Recommend

I replaced my panel with a Siemens one. So naturally I looked for a Siemens surge protector now that I had space and was modernizing things. No issues so far - not planning on having any surges, so hopefully I'll never have to report if it worked or not, but incase it happens, I feel protected.

these are surge protectors and NOT lightning.

Would Recommend

When reading thru the reviews, many talk about lightning protection. They are not. These are surge protectors, abnormally high momentary voltage spikes. Lightning arrestors are of a different design and more robust, including outside copper rods and copper wiring to earth for the incredibly high currents and voltages. Anyways easy to install when you have the compatible panel. Also, in the fine print it says the green light will blink when installed properly. When I first installed it, I ...

Good product and appears to work but really won't know until we get a lightning strike or magor surge. Easy to install (if you ever installed a circuit breaker before).
