Under Power Factor Leading Inhibit Time
Under Power Factor Leading Inhibit Time (Parameter 418) allows the installer 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 182 - Under Power Factor Leading Inhibit Time (Parameter 418)
Over Power Factor Leading Inhibit Time
Over Power Factor Leading Inhibit Time (Parameter 422) allows the installer 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 will trip 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 Delay.
