a
All circuit breakers are tested to 60 Hz; however, they can also be applied at 50 Hz with no derating.
b
K=1.0, therefore E = E/K and I = KI. Consult the Consulting Application Guide CA08104001E sections 1 and 5 for further information.
c
Consult the Consulting Application Guide CA08104001E sections 1 and 5 for further information.
d
Optional interrupting time of 3 cycles is available.
e
Tested at 28.5 kV RMS.
f
Tested at 29.5 kV RMS.
