8.8 Fuses and Circuit Breakers

Use recommended fuses and/or circuit breakers on the supply side as protection in case of component breakdown inside
the adjustable frequency drive (first fault).
NOTICE!
Use of fuses on the supply side is mandatory for IEC 60364 (CE) and NEC 2009 (UL) compliant installations.
Recommendations
•
Fuses of the type gG.
•
Circuit breakers of Moeller types. By use of other circuit breaker types, ensure that the energy into the adjustable
frequency drive is equal to or lower than the energy provided by Moeller types.
If fuses/circuit breakers according to recommendations are chosen, possible damage on the adjustable frequency drive will
mainly be limited to damage inside the unit. For further information, see Application Note Fuses and Circuit Breakers, MN90T.
The fuses below are suitable for use on a circuit capable of delivering 100,000 Arms (symmetrical), depending on the
adjustable frequency drive voltage rating. With the proper fusing the adjustable frequency drive Short Circuit Current Rating
(SCCR) is 100,000 Arms.
