Review on Adjustable AC Current Sensing Switch: SZC23 No AL-CH Model, 0.2A-30A Range by Brent Rosecrans

I bought this to tell my PLC when I turned on a piece of equipment that draws less then 1Amp. It worked for a few quick tests to verify that it could sense the low current but after I had it installed in my system the relay quite working. I never had any load applied to the switch, only a multi-meter checking for continuity and a PLC input channel.
