4.12 Active Front End unit – Circuit breaker selection
The Active Front End can also be protected by a circuit-breaker. The recommended types of circuit-
breakers are shown in Table 18. If a circuit-breaker from another manufacturer is used, it must be
equivalent to the circuit-breakers shown. Further information on the circuit-breakers shown is
available from the manufacturer. Circuit-breakers do not provide the same level of protection as
fuses. A circuit-breaker can be used without a main contactor. In this case, the Active Front End unit
controls the circuit-breaker instead of the contactor. The circuit-breakers shown are suitable for
equipment rated at 380 V–500 V or 525 V–690 V.
