1 Function Combination is NOT UL Listed

NOTES: L = Long Time (L, I 2 T) + Fuse Settings (I 4 T) (Fuse settings are now standard on all EntelliGuard ™ Trip Units) S = Short Time (Switchable if Instantaneous (I) protection is enabled) I = Standard Range Adjustable Instantaneous, (IOC, 2x-15x)

H = Extended Range Adjustable Instantaneous, (IOC, 2x-30x), Only for ANSI EntelliGuard ™ G G = Ground Fault Protection (GFP, 3-wire or 4-wire, internal summing) Trip and Alarm C = External CT for ground fault detection (AKD20 application: input from external summing CTs, used for multiple source ground fault dectection.

OEM Application: Zero Sequence Input of 1A = 100%) D = Defeatable/Switchable Ground Fault, NOT UL Listed A = Ground Fault, External Ground Fault, Alarm only GA = Ground Fault Alarm Only CA = External Ground Fault Alarm Only GDA, GCDA = Ground Fault Trip and Ground Fault Alarm (all switchable, Not UL Listed)
