Table 11.7 Fuse Options for 525-690 V Frequency Converters
For UL compliance, for units supplied without a contactor-
only option, the Bussmann 170M series fuses must be
used. See Table 11.9 for SCCR ratings and UL fuse criteria if
a contactor-only option is supplied with the frequency
converter.
11.3.3 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
100,000 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 11.8:
415 V 480 V 600 V 690 V
D6h frame 100,000 A 100,000 A 65,000 A 70,000 A
D8h frame 100,000 A 100,000 A 42,000 A 30,000 A
Table 11.8 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 11.9, the
SCCR of the frequency converter is as follows:
415 V

450 A max fuse size for D6h and 900 A max fuse size for D8h.
2) Must use Class J or L branch fuses for UL approval. 450 A max
fuse size for D6h and 600 A max fuse size for D8h.
11.3.4
Connection Tightening Torques
When tightening all electrical connections it is very
important to tighten with the correct torque. Too low or
too high torque results in a bad electrical connection. Use
a torque wrench to ensure correct torque. Always use a
torque wrench to tighten the bolts.
