Ground Fault Trip Current Level
30 mA - 9000 Amps in three ranges
Sensing Ranges Vs Trip Current Level Settings:
10 mA – 10 Amp with built-in CT .......................................................... 30 mA – 9 Amp
10 mA – 10 Amp with 500:1 external CT on terminals T1 & T2 ............ 30 mA – 9 Amp
1 - 1000 Amp with 500:5 interposing CT ....................................................3 – 900 Amp
10 - 10000 Amp with 5000:5 interposing CT ..........................................30 – 9000 Amp
Selection of each Range ...........................DIPswitch 1 on front of relay and interposing CT
Setting within each Range.....................................DIPswitches 2, 3, 4, & 5 on front of relay
Trip Current Accuracy ....................................................................+0%, -15% of trip setting
Note: The accuracy of the trip point refers to the value of the real world current
(assuming a purely sinusoidal wave shape) that just causes a trip, with
respect to the specified value in the table.
