Fuse clearing I²t values are derived from oscillograms of fuses tested within their current-limiting range and are calculated as follows: I²t = ∫tI²dt
Webthe 0.07 second clearing time criteria has been satisfied. As per Figure 2, each fuse rated 1200 A and above will have a defined ampere value on their time-current curve beyond which higher available arcing currents will result in clearing times faster than 0.07 seconds. 4. If the calculated value of arcing current is less than that which is WebClear All Brand BUSSMANN. Time-Delay UL Class L Fuses, Nonindicating.
