The fuses listed in table 49 are suitable for use on a circuit capable of delivering 100000 A
voltage rating. With the proper fusing, the drive short-circuit current rating (SCCR) is 100000 A
internal drive fusing to meet the 100 kA SCCR. E3h and E4h drives must be fitted with Type aR fuses to meet the 100 kA SCCR.
DISCONNECT SWITCH SCCR REQUIREMENTS
All units ordered and supplied with a factory-installed disconnect switch require Class L branch circuit fusing to meet the 100
kA SCCR for the drive.
If a circuit breaker is used, the SCCR rating is 42 kA. The input voltage and power rating of the drive determines the specific
-
Class L fuse. The input voltage and power rating are found on the product nameplate.
