I know this is a controls site, but hopefully you guys will be able to help me settle a discussion.
I have a 25 Amp SSR controlling a bank of heaters connected in Star.
The supply is 415, my question is....does the 25 Amps relate to Line current (Il) or Phase current (Ip), i know that with a star connection that line current (Il) = phase current (Ip) & with a delta connection phase current (Ip) = line current (Il) / 1.73
So my question is, does the stated current rating of 3 phase 415v equipment refer to line current or phase current??
Cheers
