Under kW Trip Delay
Under kW Trip Delay (Parameter 379) allows the installer to define the time
period an under real power (kW) condition must be present before a trip occurs.
It is adjustable from 0.1…25.0 seconds.

Under kW Trip Level
Under kW Trip Level (Parameter 380) allows the installer to define the real
power (kW) at which the E300 Electronic Overload Relay will trip on an under
real power (kW). It is user-adjustable from 0…2,000,000 kW.
