Circuit Breakers
Product Description
Eaton’s Cutler-Hammer dc molded
case circuit breakers are UL listed
for use in general dc circuits and
battery supply circuits of UPS systems
providing continuous, reliable ac
power to computer controlled applica-
tions such as financial transactions
and telecommunications.
For standard interrupting capacity
250 dc molded case circuit breakers.
Refer to Table 12-129 on Page 12-74.
The Series C dc breakers listed below
use the same internal and external
accessories as the standard Series C
breaker. NBDC and PBDC use the same
internal and external accessories as
standard NB and PB breakers.
Molded case circuit breakers for trans-
portation application requiring 750 Vdc
are available for certain amperages
interrupting capacity at 750 Vdc.
Breakers require 4 poles in series
for 750 Vdc application. However,
750 volt is not a UL rating. For 750 Vdc
application refer to Eaton for ordering
information. Dimensions are the same
as the standard thermal-magnetic
equivalent.
