Electrical Characteristics:
Times vs current characteristics:
The following curves indicate, for each rated current, pre-arcing time as a function of RMS value of pre-
arcing current I.
Tolerance for mean pre-arcing current ± 8%
Total clearing I²T:
Horizontal curves show, for each rated current, values of total clearing I

) as a function of
prospective current Ip @ U

with cosϕ = 0.15. Oblique lines indicate total clearing duration Tt, with
associated pre-arcing duration in brackets.
