Class 1 to 30 infinitely selectable via trip time setting: adjust from 0 to 30 Seconds, the time you set is the trip time at six times the set current. Example: 10 seconds will give a Class 10 trip.
Operational Temperature: -25 to +70 degrees C
Phase current unbalance
Phase loss/phase failure
Phase current unbalance: trips within 5 seconds when the phase current unbalance exceeds 50%.
Phase loss/phase failure: trips within 3 seconds when phase current is 70% unbalanced.
Stall Protection: Trips at 170% of full load amps at 3 seconds.
LED indication of faults for over current, phase failure.
