2.6 Cutoff Characteristics of Distribution Panel (At the time
of connecting power distribution box)
At the time of connecting the distribution panel through power distribution box, protection should be
coordinated so that the breaker of the device (or power distribution box) trips before the breaker of the
distribution panel trips. Such protection should be maintained. Therefore, the distribution panel should have
the characteristic conditions shown in “TABLE 2.5 Characteristic Condition of Distribution Panel Breaker”.
It is necessary to use Distribution panel Breaker suitable to these conditions.

Cutoff characteristic is Long-time delay type and the cutoff characteristic equivalent to D (IEC898or IN0641
part II) shown in “FIGURE 2.28 Characteristics of Breaker of Distribution Panel” or cutoff characteristics
slower than these characteristics is used.
