UL Compliance
Fuses or circuit breakers are mandatory to comply with NEC 2009. 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), 240 V, 480 V, 500 V, or
600 V depending on the unit's voltage rating. With the proper fusing, the frequency converter’s Short Circuit Current Rating
(SCCR) is 100,000 Arms.
