Will this relay work for my requirements?
« on: July 16, 2020, 06:00:48 pm »
I am trying to drive a 6A reactive load(power factor 0.6, crest factor 1.85) using a DC relay. Either 12v or 5v.
I found this relay on digikey: DATASHEET
Will this suit my requirements?

Thanks

I don't see any reactive load specifications.  So it's a crap shoot.  Best to contact the relay manufacturer and ask.

It's rated at 20 A for use with a 277 VAC lighting ballast--should be fine for your application:

OP is being a jerk, his 8-page cross-posted thread https://forum.allaboutcircuits.com/threads/critique-my-schematic.171272/page-8 he says he needs a 4-pole relay  :palm:

I am looking for replacing the 4-pole relay as they are very expensive

Lighting ballasts are commonly reactive loads. Even those in the fluorescent lights in your garage...
