Hi all,
I am a translator currently working on a switchgear manual. Under the section entitled "Ratings: Feeder/Incomer & Bus-section units", I have the following: "Rated operating sequence: 0 - 0.3 sec. - CO - 5 sec. - CO"
I don't know what to make of that bit: "0 - 0.3 sec. - CO - 5 sec. - CO". What does CO stand for here?
Thanks a lot in advance
Nina
