8.
Current values in this row are independent of
operating voltage up to and including rated
maximum voltage.
9.
Nominal three-phase MVA class" is included for
reference only. This information is not listed in
ANSI C37.06-1987.
10.
Standard duty cycle is O - 15s - CO.
11.
Standard rating interrupting time is five-cycles
(83 ms). Optional rated interrupting time of
three-cycles (50 ms) is available (except with
24 Vdc tripping).
