5.4 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 fuses, make sure to take their protective
characteristics and operational voltage into account. When using other cir-
cuit-breakers, it may be necessary to also use fuses depending on the circuit-
breaker's model, design, and settings. There may also be limitations concer-
ning the short-circuit capacity and the supply mains’ characteristic, and these
must also be taken into account when selecting circuit-breakers and/or
fuses.
