I had 2 of these that were struck by lightning. I took both apart to see what the inside looks like. The surge protector on the left was in a metal box outside with other equipment that had been struck by lightning. The lightning went through the power lines in the box and destroyed everything in the metal box including the surge protector. It looks like the surge protector didn't take a direct hit. The suppressor on the right was in a remote location where the lightning went through the ethernet cable. The muffler appears to have worked as the left side was burned while the right side showed no burn marks.
