Enter MEASURED values for Power Factor (cos )
Actual measured Power Factor will provide best accuracy as it significantly impacts ride through time.
If Power Factor is unknown estimate based on the load. For example:
Contactors and relays only - cos = 0.20
Mixed loads estimate or use - cos = 0.75
Power supplies, resistors, lamps - cos = 1.00
