Table 11: 460V, 60Hz, 3-Phase Systems
For component model numbers, see the specification tables.
For 460V systems, acceptable voltage range is 414−528V.
Maximum allowable voltage imbalance is 2%.
MCA = Minimum Circuit Ampacity.
Maximum Overcurrent Protection (MOCP) is calculated as follows: (Largest motor RLA x 2.25) + (Sum of
other motor RLA) rounded down to the nearest standard fuse size.
SCCR rating: 65 kA RMS symmetrical 460V maximum
