Table 8.7 Fuse Options for 525–690 V Frequency Converters
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 frequency converter.
8.7.2 Short Circuit Current Rating (SCCR)
If the frequency converter is not supplied with a mains
disconnect, contactor or circuit breaker, the Short Circuit
Current Rating (SCCR) of the frequency converters is
8 8
100000 amps at all voltages (380–690 V).
If the frequency converter is supplied with a mains
disconnect, the SCCR of the frequency converter is 100,000
amps at all voltages (380–690 V).
If the frequency converter is supplied with a circuit
breaker, the SCCR depends on the voltage, see Table 8.8:
D6h frame
D8h frame
Table 8.8 Frequency Converter Supplied with a Circuit Breaker
If the frequency converter is supplied with a contactor-only
option and is externally fused according to Table 8.9, the
SCCR of the frequency converter is as follows:
D6h frame
D8h frame (not
including the
N250T5)
D8h frame
(N250T5 only)
Table 8.9 Frequency Converter Supplied with a Contactor
