If the drive is supplied with a contactor-only option and is externally fused according to Table 10.14, the SCCR of the drive is
as follows:

Table 10.14 D6h and D8h Supplied with a Contactor
1)
With a Bussmann type LPJ-SP or Gould Shawmut type AJT fuse. 450 A maximum fuse size for D6h and 900 A maximum fuse size for D8h.
2) Must use Class J or L branch fuses for UL approval. 450 A maximum fuse size for D6h and 600 A maximum fuse size for D8h.
E1h–E4h recommended fuses
The fuses listed in Table 10.15 are suitable for use on a circuit capable of delivering 100000 A
the drive voltage rating. With the proper fusing, the drive short circuit current rating (SCCR) is 100000 A
drives are supplied with internal drive fusing to meet the 100 kA SCCR and to comply with UL 61800-5-1 enclosed drive
requirements. E3h and E4h drives must be fitted with Type aR fuses to meet the 100 kA SCCR.

NOTICE
DISCONNECT SWITCH
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 is found on the product
nameplate. For more information regarding the nameplate, see the operating guide.
