Electrical Data Table Information
Compressor motor electrical data is provided in Table 9, p.
36 for each compressor size. Rated load amperes (RLA),
locked rotor wye amperes (LRA) and expected inrush for
the Wye-delta configurations are shown.
Although the terms “LRA” and “expected inrush” are often
used interchangeably, the distinction applied here is that
LRA is the rated inrush for the motor, but expected inrush is
that allowed by the starter, based on the specific
configuration. Selecting starters in the Wye-delta
configuration lowers expected inrush vs. the across-the-
line configuration.
The RLA is based on the motor’s performance when
reaching full rated horsepower. The kW rating of the motor
will equal or exceed the kW requirement indicated by the
Trane® Select Assist™ selection program at design
conditions. If motor kW draw at design conditions is less
than the kW rating of the motor, the RLA at design
conditions is determined by multiplying the motor RLA (at
the desired voltage) by this ratio: design kW/ motor kW
rating. This calculation is performed within the computer
selection program, making RLA available as part of the
design predictions. Predicted values include power factor
variation from point to point.
Optimus™ chillers are designed to operate satisfactorily
over a utilization range of ±10 percent of the standard
design voltages: 200V, 230V, 380V, 460V, and 575V for 60
Hertz, 3-phase.
