6.5 Fuses
The Eaton circuit-breakers and fuses listed below are examples and can be
used without additional measures. If you use other circuit-breakers and/or
fuses, make sure to take their protection characteristics and operational
voltages into account. When using other circuit-breakers, it may be
necessary to use fuses as well, depending on the circuit-breaker’s model,
design, and settings. There may also be limitations concerning the short-
circuit capacity and the supply network's characteristic, and these must also
be taken into account when selecting circuit-breakers and/or fuses.
