LRA stands for "Locked Rotor Amps," which refers to the current that an electric motor, such as an air conditioning compressor, draws when the rotor is locked and unable to turn. The LRA rating is used to determine the electrical protection and circuitry requirements for the compressor.
The Locked Rotor Amps (LRA) of a 2HP (Horsepower) air conditioning compressor can vary depending on the specific model and manufacturer. However, as a general guideline, the LRA for a 2HP air conditioning compressor typically falls within the range of 40 to 70 amps.
It's important to note that the LRA is a peak value, and under normal operating conditions, the compressor's running current will be significantly lower than the LRA. Proper circuit protection, such as fuses or circuit breakers, should be installed to handle the peak LRA without tripping, while also providing adequate protection during normal operation. Always refer to the manufacturer's specifications or consult with a qualified HVAC technician to ensure proper electrical installation and safety.
