Binary function link string, selecting which
overcurrent elements (stages 1 to 4) will be
blocked if VTS detection of fuse failure
occurs.
Inverse time (IDMT) characteristic
IDMT characteristics are selectable from a
choice of four IEC/UK and five IEEE/US curves
as shown in the table below.
The IEC/UK IDMT curves conform to the
following formula:
