LRA stands for Lock Rotor Ampere on compressor and means that it is a high inrush current during starting period of the compressor.

LRA stands for locked rotor amps. It is the very high current drawn by a motor at the instant it receives power, but before the motor has started to turn. Typical LRA values can be anywhere between 3 and 8 times the full-load running current.
Locked rotor ampere
Each motor has a published manufacturer Lock Rotor Amperage (LRA) rating that is used to obtain this ratio. If a manufacturer otained a reading of 100A while bench testing their motor (equipment) at full load, if the motor FLA (Full Load Anps) is 50 amps, the raito LRA to FLA is 2 to 1 or 200%.
LRA (locked rotor amps) is not used to calculate the breaker size. Breaker's are used to protect the size of the conductor that is connected to it. Motor calculations are based on the motor's FLA (full load amps).Conductor size is 125% of the motor's FLA.Breaker size is 250% of the motor's FLA.This is the only occasion when the breaker is sized larger that the conductors maximum amperage rating. This is due to the motor drawing up to 300 to 600% of its FLA when starting.If you state the motor's wattage, voltage or amperage this calculation can be calculated here.
There are several different reasons. 1 acid in system 2 constant overheating of compressor 3 voltage surges 4 lightning strike
