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, or 480 V, or 500 V,
or 600 V depending on the frequency converter voltage rating. With the proper fusing the frequency converter Short Circuit
Current Rating (SCCR) is 100,000 Arms.
