DC Application Data Peak Arc voltage vs. working voltage
Time vs. current characteristics
Above: Curves indicate maximum permissible value of time
constant L/R as a function of DC working voltage.
Max. AC voltage (50/60 Hz): 1250V with interrupting rating
of 170kA.
1-L/R = 100ms
2-L/R = 40ms
Above: Curves indicate for various time constants L/R the peak
arc voltage which may appear across fuse terminals, vs. DC
working voltage.
Above: Curves indicate, for each rated current, pre-arcing time
vs. R.M.S. pre-arcing current.
