Electrical Characteristics:

Times vs current characteristics

The curves shown on page 4 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.
