I have a board populated with Omron relays (G5Q-1A4-EU DC5) and I want to use them to switch circulation pumps (https://imp-pumps.com/pumps/ghn/). Is the previous relay appropriate to be used with said pumps?
From the information available on the pumps, they seem to act as a resistive load during operation. Is this behaviour only expected when they're under full load? If the relay switches off the pump while acting as a resistive load, is there a danger of an overvoltage appearing on the relay contacts?
If the relay mentioned previously is not suitable for this application, could it still be used if paired with the appropriate protection components? What would be the most suitable protection in this particular application? And if not, what kind of relay would be suitable for this application?
I know I just asked a ton of questions, but any help would be greatly appreciated. Thank you.
