How is a compressor's rated load amp rating (RLA) determined?

The rated load amp rating (RLA) of a compressor is a vital parameter that reflects the operational characteristics of the compressor under normal conditions. The correct determination of RLA is based on the maximum continuous current rating, which is then adjusted. The process typically divides this maximum rating by a specific factor, which is often set at 156 for typical compressor applications. This division accounts for the running conditions under standard operating parameters, ensuring that the compressor operates efficiently without exceeding its designed electrical load.

Understanding this method of calculating RLA helps users evaluate the performance and energy consumption of compressors during regular operations. It ensures that the compressor can run effectively without overheating or risking damage from excessive current. The focus on a consistent factor for this calculation signifies industry standards that prioritize reliability and safety in compressor operations.
