8.8 Fuse Specifications

It is recommended to use fuses and/or circuit breakers on the supply side as protection in case of component break-down
inside the frequency converter (first fault).
NOTICE
This is mandatory in order to ensure compliance with IEC 60364 for CE or NEC 2009 for UL.
The fuses below are suitable for use on a circuit capable of delivering 100,000 Arms (symmetrical), depending on the
frequency converter voltage rating. With the proper fusing the frequency converter Short Circuit Current Rating (SCCR) is
100,000 Arms.
