Trip Currents 5 - 60 , 3 0 - 360 , or 10 0 -1 2 0 0 A
fault current on a ground ac power system. When a ground fault exceeds a pre-selected Current level and Time Delay
setting, the relay initiates a trip signal for a shunt trip disconnect device to open and clear the fault . This BGFL system
is designed to provide protection for electrical equipment , not protection for personnel.
These Class 1 Model BGFL Ground Fault Relays and Sensors are designed to form a system for detecting a ground
