Electrical Characteristics:
Times vs current characteristics
The following curves indicate the pre-arcing time for each rated current as a function of RMS value of
pre-arcing current I:
-
Tolerances on this current ± 8%
-
Beyond 30 sec or 10 sec, small overloads must be eliminated by another device.
