WebHere, as defined in IEC 60255, the IDMT Tripping Time T (s) is multiplication of Time Setting Multiplier (TSM) by the k curve constant divided by the division of fault current I (F) in Amps to relay Current setting Is (A) in amps power of curve constant α minus 1. Hence the formula can be written as, T (s) = TSM * (k / ( (I (F) /Is (A) ) α ... WebTripping curves - Acti 9 breakers The following curves show the total fault current breaking time, depending on its amperage.
