Seems like it, although it has two three "combined" wires going into each side, one wire going to a plug socket, and the other going through a plug socket to the mains. So it looks like it dosen't gate current at all, it's merely some kind of thing in series with the other plugs. To BurningTantalum: No idea what the model is, but looks like some kind of acrylic package with LEDs inside, although they're not bright enough, and it vaguely looks like there's 2 LEDs inside.
