Product Description
UL listed DC Molded Case Circuit
Breakers for use in general DC circuits
and ungrounded battery supply circuits
of UPS systems providing continuous,
reliable AC power to computer con-
trolled applications such as financial
transactions and telecommunications.
For standard interrupting capacity
250 DC molded case circuit breakers.
Refer to Table 12-1.
The Series C DC breakers listed below
use the same internal and external
accessories as the standard Series C
breaker. NBDC and PBDC use same
internal and external accessories as
standard NB and PB breakers.
Molded case circuit breakers for trans-
portation application requiring 750V DC
are available 15 – 2500 ampere 20 kA
interrupting capacity at 750V DC.
Breakers require 4 poles in series for
750V DC application. However, 750V is
not a UL rating. For 750V DC application
refer to Cutler-Hammer for ordering
information. Dimensions are the same
as the standard thermal-magnetic
equivalent.
Technical Data
and Specifications
Interrupting Capacity Ratings
Table 12-272. UL489 Interrupting
Capacity Ratings
DC ratings apply to substantially non-
inductive circuits. 8 millisecond time constant.
1 pole in series.
2 poles in series.
3 poles in series.
4 poles in series. Not a UL listed voltage
rating.
Wiring Diagrams
