Under Power Factor Leading Inhibit Time
Under Power Factor Leading Inhibit Time (Parameter 418) allows you to inhibit
an under power factor leading trip and warning from occurring during the motor
starting sequence. It is adjustable from 0…250 seconds.
Table 286 - Under Power Factor Leading Inhibit Time (Parameter 418)
Over Power Factor Leading Inhibit Time
Over Power Factor Leading Inhibit Time (Parameter 422) allows you to inhibit
an over power factor leading trip and warning from occurring during the motor
starting sequence. It is adjustable from 0…250 seconds.

Under Power Factor Lagging Trip
The E300 Electronic Overload Relay trips with an Under Power Factor Lagging
indication if:
• No trip currently exists
• Under Power Factor Lagging Trip is enabled
• Current is present
• Voltage is present
• Under Power Factor Lagging Inhibit Time has expired
• The total power factor lagging is less than the Under Power Factor Lagging
Trip Level for a time period greater than the Under Power Factor Lagging
Trip D elay.
