Selection Procedures
• RLA = Rated Load Amps
• Compressor LRA = Locked Rotor Amps
• Compressor Input = VFD drive Input
• Compressor Output = VFD drive output
• Voltage utilization range is ±10%
Determination of Minimum Circuit
Ampacity (MCA)
MCA = 1.25 x Largest motor amps/VFD Input + the sum of
the remaining motor amps.
Determination of Max Fuse (MFS) and Max
Circuit Breaker (MCB) Sizes
MFS and MCB = 2.25 x Largest motor amps (RLA)/VFD
input) + the sum of the remaining motor amps.
If the rating value calculation does not equal a standard
over current protective device rating, use the next lower
standard rating as the maximum.
