2.9.3 Breaker characteristics
The breaker characteristics for the SPARC M10 systems must be taken into consideration to allow the devices to be used under the right conditions. Use circuit breakers that meet the following special conditions for the distribution panel breakers on the equipment side.

Table 2-17 shows the distribution panel breaker capacity on the equipment side.

Figure 2-24 shows the cutoff characteristics of the circuit breaker.

Use a breaker with cutoff characteristics that have a Long-time delay type equivalent to cutoff characteristic D (IEC/EN60898 or DIN VDE 0641 part II) shown in Figure 2-24, or one with longer cutoff characteristics.
