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 characteristic and operational
voltage into account. When using other circuit-breakers, it may be necessary
to also use fuses 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.
