DC applications data
Time vs. current characteristics
Peak arc voltage
vs. working voltage
Above: Curve indicates maximum permissible value of time
constant L/R as a function of DC working voltage
1 : L/R = 15 ms 4200 V SRF-SRH
2 : L/R = 45 ms 4200 V SRF-SRH
Max. AC voltage (50/60 Hz):
3,800 V with breaking capacity of 50 kA
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
