1. Refer to General Data Section for standard fan motor size on units.
2. FLA = Full Load Amps (does not reflect typical operating amps)
WSA = Wire Sizing Amps (Minimum supply circuit ampacity)
MFCB = Maximum Fuse or Circuit Breaker Size
3. Amperage requirements are based on the rated max FLA current of each component in the unit. The rated
max FLA current of the unit is not the sum total of all components, but is the total of the components which
operate during maximum electrical load conditions.
4. The values in the chart are for power of the unit only.
5. Units are 3 phase, 60 cycle.
6. For units with other variations not listed above, consult your Emerson representative for electrical
requirements.
7. SCCR - Short Circuit Current Rating 65,000 rms (less than 480V), 25,000 rms (575V).
