Fusible overcurrent protectors cannot operate at first-level current levels. Thus, the permissible low current time-current boundary for fusible
overcurrent protectors is formed by the first-level test currents. Automatically resettable overcurrent protectors (e.g. Positive Temperature
Coefficient Thermistors) may operate during first-level testing, but normal equipment working must be restored after the test has ended.
At system level, the high current boundary is formed by the unacceptable region. However, component and printed wiring, PW, current
limitations will typically lower the high current boundary. Although the series line feed resistance, R
second-level testing, after about 0.5 s this limitation will exceed the acceptable current flow values.
These three boundaries, first-level, second-level and unacceptable, are replotted in terms of peak current rather than rms current values in
Figure 19. Using a peak current scale allows the TISP61089B longitudinal current rating curves (Figure 3) to be added to Figure 19. Assuming
the PW is sized to adequately carry any currents that may flow, the high current boundary for the overcurrent protector is formed by the
TISP61089B rated current. Note that the TISP61089B rated current curve also depends on the value of gate supply voltage.
Dedicated intra-building ports may use an R
single cycle rating. For the TISP61089B to survive the full 900 s test, the series overcurrent protection to operate before the TISP61089B
current-time ratings are exceeded.
To meet ‘1089, the overcurrent protection must be coordinated with the requirements of Sections 4.5.7, 4.5.8, 4.5.9, 4.5.12, 4.5.13, 4.5.15 and
the TISP61089B. The overcurrent protection must not fail in the first-level tests of Sections 4.5.7, 4.5.9 and 4.5.12 (tests 1 through 5). Test 6
through 9 of Section 4.5.12 are not requirements. The test current levels and their duration are shown in Figure 18. First-level tests have a high
source resistance and the current levels are not strongly dependent on the TISP61089B series resistor value.
Second-level tests have a low source resistance and the current levels are dependent on the TISP61089B R
lines at the top of Figure 18 are for the 25 Ω and 40 Ω series resistor cases. The unacceptable current region (Section 4.5.11) is also shown in
Figure 18. If current flows for the full second-level test time, the unacceptable current region will be entered. The series overcurrent protector
must operate before the unacceptable region is reached.
