L1 Under Current Trip Delay
L1 Under Current Trip Delay (Parameter 266) allows you to define the time
period an L1 Under Current condition must be present before a trip occurs. It is
adjustable from 0.1…25.0 seconds.

L1 Under Current Trip Level
L1 Under Current Trip Level (Parameter 267) allows you to define the current at
which the E300 relay trips on a L1 Under Current. It is user-adjustable from
10…100% of the FLA Setting (Parameter 171).
IMPORTANT
The Protection Fault State of Relay 0, Relay 1, Relay 2, Digital Module 1 Output
