LRA is the higher average current as measured on
a mechanically blocked compressor tested under
nominal voltage. LRA is printed on the name-
plate.
The LRA value can be used as a rough estimation
for the starting current. However in most cases,
the real starting current will be lower. Many coun-
tries have defined limits for the starting current in
domestic use. A soft starter can be applied to re-
duce starting current.
The MCC is the current at which the internal mo-
tor protection trips under maximum load and low
voltage conditions.
This MCC value is the maximum at which the com-
pressor can be operated in transient conditions
and out of the application envelope. Above this
value the overload will switch off to protect the
motor.
The Max Oper. A is the current when the compres-
sor operates at maximum load conditions and
10% below nominal voltage.
This value which is the max rated load current for
the compressor is new on the nameplate.
Max Oper. A can be used to select cables and con-
tactors.
In normal operation, the compressor current
consumption is always less than the Max Oper. A
value.
