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 24. 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 same level of protection as fuses,
therefore, fuses are always recommended to be used. 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.
