Locked Rotor Amp value is the higher average
current as measured on mechanically blocked
compressor tested under nominal voltage. The
LRA value can be used as rough estimation for
The MCC is the current at which the motor
protection trips under maximum load and
low voltage conditions. This MCC value is the
maximum at which the compressor can be
operated in transient conditions and out of

the starting current. However in most cases, the
real starting current will be lower. A soft starter
can be applied to reduce starting current.

internal motor protection or external electronic
module will cut-out the compressor to protect
the motor.
