Westcode Semiconductors F070AxxxN Tripping Curves

WESTCODE An IXYS Company French Ferrule Type Fuses 660/700V

Electrical Characteristics:

Times vs current characteristics

The following curves indicate, for each rated current, pre-arcing time as a function of RMS value of pre­arcing current I.

Tolerances on this current: ±10% = ratings from 1 to 6A

± 9% = ratings from 8 to 30-32A

Fuse 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.

I ≤ 6I ≥ 8

Cut off Characteristics:

The curves below indicate, for each rated current, the peak value Ic that the current may reach as a
function of prospective fault current Ip.

I ≤ 6I ≥ 8
