The lifespan of a 3-phase motor run capacitor can vary depending on factors such as usage, operating conditions, and quality of the capacitor. On average, they can last anywhere from 5 to 10 years, but it is recommended to regularly check and replace capacitors if needed to maintain optimal motor performance.
