1 Cutler-Hammer Westinghouse & Cutler-Hammer Products Five Parkway Center Pittsburgh, Pennsylvania, U.S.A. Application Data -C Page October Mailed to: E/-A Time/Current Characteristic Curves for Westinghouse Current Limit-R Circuit Breakers and Tri-Pac Circuit Breakers Westinghouse AB DE-ION Current Limiting Circuit Breakers Voltages shown in curve headings are maximum at which the breaker may be applied. Interrupting capacity of individual breaker is tabulated on each curve. Individual oversize copies of curves listed above printed on onion-skin paper are available in limited quantity from: Cutler-Hammer Westinghouse & Cutler-Hammer Products Five Parkway Center Pittsburgh, PA When ordering onion-skin curves, use number at bottom of page where curve appears, i.e., SC-4-.
