Final answer:
AFL means Amps Full Load, and RLA means Rated Load Amps on a contactor or relay, both indicating important electrical parameters for device operation.
Step-by-step explanation:
On a contactor or relay, AFL stands for Amps Full Load and RLA stands for Rated Load Amps. These abbreviations are associated with electrical parameters important for correctly sizing and applying contactors and relays in various electrical circuits. Amps Full Load refers to the current drawn by an electrical device when it operates at its full-rated load. It is the maximum current that the device should pull under full-load conditions. Rated Load Amps, on the other hand, represents the maximum steady-state current that a contactor or relay can handle while controlling a specific load.
