9.3.1.3 CE Compliance
Fuses or circuit breakers are mandatory to comply with IEC 60364. Danfoss recommend using a selection of the following.
The fuses below are suitable for use on a circuit capable of delivering 100,000 A
690 V depending on the adjustable frequency drive voltage rating. With the proper fusing the adjustable frequency drive
short circuit current rating (SCCR) is 100,000 A
The following UL-listed fuses are suitable:
•
UL248-4 class CC fuses
•
UL248-8 class J fuses
•
UL248-12 class R fuses (RK1)
•
