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 transportation 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.
