Interrupting capacity of inidvidual breaker is tabulated on 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.
