Page 11
A simulated current equal to 120% of the trip current set on the Trip Level DIPswitches
replaces the measured current. This tests all internal electronics and secondary winding of the
built-in current transformer. No external power supply or additional wiring is required.
Remote Test ........................................................ Double click button connected to terminals R1 and R2
Remote Reset (Non-Failsafe mode only) ..............N.O. Reset button connected to terminals R1 and R2
Reset mode ............................................................................................... Manual or Pulsed Auto Reset
Ground Fault Circuit:
Ground Fault Trip Time Delay......................................................................... 20 or 500 milliseconds
Setting ............................................................................................ DIPswitch 4 on front of relay

Ground Fault Trip Current Level
30 mA – 6.0 Amps in 8 settings: 30mA, 120mA, 210mA,
300mA, 600mA, 2.4Amps, 4.2Amps, and 6.0Amps
Setting within the Range.................................................DIPswitches 1, 2, & 3, on front of relay
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.
