I am reading some materials about reclosers, specifically, Cooper/Eaton Form 6 recloser. One thing I have been unable to determine is what a 52 a or b contact is. I looked up "52a Recloser" on Google and found that this applies to multiple manufacturers of reclosers.
Does anyone know what this term means?
Here is a quote from Cooper's manual:
"There are several conditions that will cause the alternate
blinking of the CONTROL LOCKOUT, RECLOSER OPEN,
and RECLOSER CLOSED LEDs: Failure to Trip, Failure to
Close, Interrupter Malfunction, and 52a/b Disagreement."
