Table 8.7 Fuse Options for 525–690 V Adjustable Frequency drives
For UL compliance, use the Bussmann 170M series fuses for units supplied without a contactor-only option. See Table 8.9 for
SCCR ratings and UL fuse criteria if a contactor-only option is supplied with the adjustable frequency drive.
8.7.2 Short Circuit Current Rating (SCCR)
If the adjustable frequency drive is not supplied with a line power disconnect, contactor or circuit breaker, the Short Circuit
Current Rating (SCCR) of the adjustable frequency drives is 100000 amps at all voltages (380–690 V).
If the adjustable frequency drive is supplied with a line power disconnect, the SCCR of the adjustable frequency drive is
100,000 amps at all voltages (380–690 V).
If the adjustable frequency drive is supplied with a circuit breaker, the SCCR depends on the voltage, see Table 8.8:
