1)
Circuit breakers equipped with integral trip units have a making current release set to trip instantaneously at 25 x I
n
peak current to prevent closing
on a fault current exceeding that magnitude.
2)
Magnum ACB’s carry an IT rating at 440 Vac per IEC 60947-2 Annex H. Contact Eaton for 690 Vac IT applications.
3)
The I
cw
1
sec/3 sec rating is 50/30 kA for 2000 A MWN 50 kA breaker.
4)
Standard frame circuit breakers rated 100 kA are equipped with a high instantaneous trip set to protect above 85 kA
rms
.
I
cu
is 100 kA and I
cs
is 85 kA at 440 Vac.
I
cu
and I
cs
are 85 kA at 690 Vac.
5)
The approximate weights and dimensions shown are based on horizontal terminals.
6)
Close and latch ratings are applicable only to non-automatic switches. Non-automatic switches should be applied with a suitable external overcurrent device with
instantaneous trip to protect above the published close and latch rating.
7)
The maximum available instantaneous interrupting rating for the standard frame non-automatic switch is 85 kA.
