Protective Trip and Warning Functions Chapter 5
Under kVAR Generated Inhibit Time
Under kVAR Generated Inhibit Time (Parameter 394) 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 158 - Under kVAR Generated Inhibit Time (Parameter 394)
Over kVAR Generated Inhibit Time
Over kVAR Generated Inhibit Time (Parameter 398) allows the installer to
inhibit an over reactive power (kVAR) generated trip and warning from
occurring during the motor starting sequence. It is adjustable from 0…250
seconds.

Under kVAR Consumed Trip
The E300 Electronic Overload Relay will trip with an Under kVAR Consumed
indication if:
• No trip currently exists
• Under kVAR Consumed Trip is enabled
• Current is present
• Voltage is present
• Under kVAR Consumed Inhibit Time has expired
• The total reactive power (kVAR) consumed is less than the Under kVAR
Consumed Trip Level for a time period greater than the Under kVAR
Consumed Trip Delay.
If the E300 Electronic Overload Relay trips on an under reactive power (kVAR)
consumed, the:
