3.4.3 CE Compliance
Fuses or circuit breakers are mandatory to comply with IEC
60364. Danfoss recommends using a selection of the
following.
The fuses below are suitable for use on a circuit capable of
delivering 100,000 Arms (symmetrical), 240V, 480V, 500V,
or 600V depending on the unit's voltage rating. With the
proper fusing, the frequency converter short circuit current
rating (SCCR) is 100,000 Arms.
