Current Imbalance Trip Delay
Current Imbalance Trip Delay (Parameter 260) allows you to define the time
period a current imbalance condition must be present before a trip occurs. It is
adjustable from 0.1…25.0 s.

Current Imbalance Trip Level
Current Imbalance Trip Level (Parameter 261) allows you to define the
percentage at which the E300 Electronic Overload Relay trips on a current
imbalance. It is user-adjustable from 10…100%.
