Protective Trip and Warning Functions
Power Factor Protection
The E300 Electronic Overload Relay has the capability to help protect against
power factor for specific applications that require the monitoring of both voltage
and current. You can help protect or issue a warning if the power factor of an
electric motor is either too high or too low.
Under Power Factor Lagging Inhibit Time
Under Power Factor Lagging Inhibit Time (Parameter 410) allows you to inhibit
an under power factor lagging trip and warning from occurring during the motor
starting sequence. It is adjustable from 0…250 seconds.
Table 284 - Under Power Factor Lagging Inhibit Time (Parameter 410)
Over Power Factor Lagging Inhibit Time
Over Power Factor Lagging Inhibit Time (Parameter 414) allows you to inhibit
an over power factor lagging trip and warning from occurring during the motor
starting sequence. It is adjustable from 0…250 seconds.
Table 285 - Over Power Factor Lagging Inhibit Time (Parameter 414)
IMPORTANT
The Over kVA Warning function does not include a time delay feature. Once the
Over kVA Inhibit Time has expired, the Over kVA Warning indication is
instantaneous.
