4 Time Delay Curves 000 OPERATING CHARACTERISTICS 00 CURVE 1 0 Tripping Time (Seconds) Maximum Minimum % Rated Current * The published time delay curves are generated at 30 o C ambient temperature with the Circuit Breaker mounted in the up-right position. The must hold, must trip and instantaneous trip current values are not affected by temperature, although delay time for the other operating current values may have to be adjusted using the temperature compensation curve which is available on request.
