Rated Load Amperage (RLA). As it relates to HVACR, Rated Load Amperage (RLA) is a mathematical calculation used to get Underwriters Laboratories (UL) approval for a certain compressor motor. It should not be confused with Full Load Amps (FLA).
Accordingly, what does LRA and RLA mean?
LRA is Locked Rotor Amperes (max current spike during a motor start) RLA is Rated Load Amperes (same thing as FLA) FLA is Full Load Amperes (fully loaded motor current)
What are locked rotor amps?
Locked Rotor Amps, sometimes abbreviated LRA, is exactly what the name implies. If the rotor is locked and can't move while electrical power is applied, the motor will draw this many amps. Locked Rotor Amps are much higher than running amps, generally around five times max running amps.
What is meant by LRA?
The Lord's Resistance Army (LRA), also known as the Lord's Resistance Movement, is a rebel group and heterodox Christian cult which operates in northern Uganda, South Sudan, the Central African Republic, and the Democratic Republic of the Congo.
