Q: Can this use for water pump auto on & off?

Asked by shashika danushka on 2019-03-18 11:18:25

mitch Iuse it to run a 24 volt, 60 watt, DC pump in my garden. However I would not recommend it for a mains powered water pump due to the higher current draw, especially when the pump starts. You could easily wire this relay to operate a secondary relay to run mains powered pump.
