2.6 Circuit Breaking Characteristics
This section describes the circuit breaking characteristics.
(1) For customers in Japan
Table 2.6 lists the requirements for the circuit breakers. Figure 2.24 shows the
characteristics of such circuit breakers.
Main unit (480/440 base cabinet)
Extended power cabinet
The breaking capacity must be 30 A or
greater. The tripping time must be equal to
or slower than the characteristics shown in
Figure 2.24
If breakers other than those specified above are used, they may be tripped at the
occurrence of a device-internal short circuit, which in turn may cause the entire
device to shut down. This may occur even if a PSU is present that provides a
redundant configuration.
