UL Compliance
Fuses or Circuit Breakers must 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, or 480 V, or
500 V, or 600 V depending on the adjustable frequency
drive voltage rating. With the proper fusing, the drive
Short Circuit Current Rating (SCCR) is 100,000 Arms.
