Relay question
Posted: Sun Feb 09, 2020 12:04 pm
I am looking for a low profile, 2-pole contactor for my ChaDeMo port. I have a few Finder 30A relays here similar to this: https://www.reichelt.de/leistungsrelais ... 7.html?r=1
It has 30A switching capability. It will never switch under load. Does it mean its conducting capability is higher? By how much?
I loaded it down with 27A today and thereby found it has 1.5mOhm resistance measured from the inputs. With R*I² we get losses per contact of
Alternatively I have a 400A KiloVAC contactor here.

- 1.35W @ 30A
- 2.4W @ 40A
- 3.75W @ 50A
- 5.4W @ 60A
