Table 100 - L3 Under Current Trip Delay (Parameter 272)
L3 Under Current Trip Level
L3 Under Current Trip Level (Parameter 273) allows the installer to define the
current at which the E300 Electronic Overload Relay will trip on a L3 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
Relays, Digital Module 2 Output Relays, Digital Module 3 Output Relays, and
Digital Module 4 Output Relays are defined by the respective parameters:
• Output PT00 Protection Fault Action (Parameter 304)
• Output PT00 Protection Fault Value (Parameter 305)
• Output PT01 Protection Fault Action (Parameter 310)
• Output PT01 Protection Fault Value (Parameter 311)
• Output PT02 Protection Fault Action (Parameter 316)
• Output PT02 Protection Fault Value (Parameter 317)
• Output Digital Module 1 Protection Fault Action (Parameter 322)
• Output Digital Module 1 Protection Fault Value (Parameter 323)
• Output Digital Module 2 Protection Fault Action (Parameter 328)
• Output Digital Module 2 Protection Fault Value (Parameter 329)
• Output Digital Module 3 Protection Fault Action (Parameter 334)
• Output Digital Module 3 Protection Fault Value (Parameter 335)
• Output Digital Module 4 Protection Fault Action (Parameter 340)
• Output Digital Module 4 Protection Fault Value (Parameter 342)
IMPORTANT L3 Under Current Trip Delay (Parameter 272) allows the installer to define the
time period an L3 Under Current condition must be present before a trip occurs.
