Size: 10x38
The fuse preselection table below indicates:
- rated current (or rating) IN
- pre-arcing I2t (I2tp) at 1 ms
- total operating I2t (I2tt) at 690V, cos ϕ=0.15, and for a total operating time from 8 to 10 ms
- dissipated power PNat the rated current IN, and at 0.8 IN, in steady state
- Nominal breaking capacity, checked by tests made in accordance with IEC standard.

Above: Curve indicating the maximum time constant
L/R of the fault path as a function of the DC voltage U,
for the rated currents from 1 to 30 A of this range.
Time-current characteristics: Curves indicate, for each
rated current, pre-arcing time as a function of RMS
value of pre-arcing current I.
Tolerances on this current:
±10% = ratings from 1 to 6 A
±9% = ratings from 8 to 30 A
Fuses with “gR” characteristics can eliminate all overloads.
They do not show any minimum breaking capacity but limit currents of
non-operation or operation in compliance with standard VDE 636/23.
Cut off characteristics: Curves indicate, for each rated current, the peak
value Ic that the current may reach as a function of prospective fault cur-
rent Ip.
