Usually rated for full 5 amps, but often they will say X amps (inductive), X amps (resistive) so type of load supplied needs consideration. Some contacts may have a tungsten filament rating as well.Anyone know if relays are rated at 100 percent?
Example a 5 amp contact current listed ice cube relay. Good for 5 amps continous current or would you have to derate like a breaker to 80 percent load (4) amps?

5A was otherwise noted - take that to mean whatever you want, I'm generally only using that one for pilot duty though.I would not derate, however, keep in mind that these type of relays are usually only suitable for pilot duty unless otherwise noted.
The ampacity that is actually switched is a total of 1.7 amps. Three very small 1 phase 120v AC magnetic induction pumps.
My thought is if its rated at 5 amps 250v (1250 watts) and I'm switching a 120v 1.7 amp load (204) watts. Seems well within its AC listed capacity range.
Thoughts?
Often the details for the ratings with an inductive load are hard to find in the specs. Do you have a part number and brand for the relay you are planning on using?
I really don't think it works that way, but I could be wrong.@250 it wont, but what would be the 125 volt equivalent ampacity alowance?...if its 1/2 the voltage should be close to double the amps which would be right at 1.6amp just shy of my 1.7 max I'm getting.
Should be right at the rating for it.
From what i read damage to contacts will be from switching the load and its rated at 500VA. Im at 204VA.
I really don't think it works that way, but I could be wrong.
That relay would likely be one and done at 1.7A inductive...
