UL Compliance
Fuses or Circuit Breakers are mandatory to comply with NEC 2009. We recommend using a selection of the following
The fuses below are suitable for use on a circuit capable of delivering 100,000 Arms (symmetrical), 240V, or 480V, or 500V,
or 600V depending on the frequency converter voltage rating. With the proper fusing the drive Short Circuit Current Rating
(SCCR) is 100,000 Arms.
