Danfoss FC 301 Operating Guide

8.7 Fuses and Circuit Breakers
Use recommended fuses and/or circuit breakers on the supply side as protection if there is component break-down inside
the frequency converter (rst fault).
NOTICE
Use of fuses on the supply side is mandatory for IEC 60364 (CE) and NEC 2009 (UL) compliant installations.
Recommendations
•
gG type fuses.
•
Moeller type circuit breakers. For other circuit breaker types, ensure that the energy into the frequency converter is
equal to or lower than the energy provided by Moeller types.
Use of recommended fuses and circuit breakers ensures that possible damage to the frequency converter is limited to
damage inside the unit. For further information, see Application Note Fuses and Circuit Breakers.
The fuses in chapter 8.7.1 CE Compliance to chapter 8.7.2 UL Compliance are suitable for use on a circuit capable of delivering
100000 A
rms
(symmetrical), depending on the frequency converter voltage rating. With the proper fusing, the frequency
converter short-circuit current rating (SCCR) is 100000 A
rms
.
