* The published time delay curves are generated at 30oC 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.
