Correction Factor, Peak Arc Voltage and
I2t Multiplier Coefficient
Peak Arc Voltage
The above Mean curve shows variation of total
clearing time (I2tt) and total operating time Tt in
accordance with working voltage U.
Curve indicating peak arc voltage Um which may
appear across fuse terminals as a function of
working voltage U @ cos
= 0.15.
Dissipated Power
Curve enabling calculation of dissipated power P
by a fuse rated IN, as a function of the RMS
current I, in multiples of IN in a steady state.
