Table 10.7 Fuse Options for 525–690 V Adjustable Frequency Drives
For UL compliance, for units supplied without a contactor-
only option, the Bussmann 170M series fuses must be
used. See
Table 10.9
for SCCR ratings and UL fuse criteria if
a contactor-only option is supplied with the adjustable
frequency drive.
10.3.3 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 100,000 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 10.8
:
