Note:Time/Current characteristic curves for Series C J-frame circuit breakers--voltages shown in curve headingsare maximum at which the breaker may be applied . Interrupting capacity of inidvidual breaker is tabulatedon each curve .

Note:The following curves are UL489 Listed for use in North America .The following circuit breakers are derived from Eaton, Westinghouse, or Cutler-Hammer history .

Time Current Curves are engineering reference documents for application and coordination purposes only. For field testing molded case circuit breakers, refer to NEMA AB 4 guidelines.
