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

Bought this relay to replace a salt chlorine flow switch that kept having issues and not triggering despite flow. Installed (wire one leg of the pump power through the sensor) and working within 15 minutes after receiving from Revain - doesn't get better.Disclaimer: Use for this application with caution - it is better to get a flow switch to work
