QF(18) - Series Miniature Circuit Breakers Time Delay Curves 1500 Tripping Time (Seconds) % Rated Current * The published time delay curves are generated at 25oC 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.
