Ir = Long-Time Pickup (LTPU) = In x Ir Dial (think QO breaker handle rating)tr = Long-Time Delaytr Long Time Delay

Isd = Short-Time Pickup (STPU) = Ir x Isd Dialtsd = Short-Time Delay

Ii I t t Pi k I Ii Di lIi = Instantaneous Pickup = In x Ii Dial

Ig = Ground-Fault Pickup = based on Sensor Plug In, see table on trip unit pagetg = Ground-Fault Delay

In = Sensor Plug Rating = maximum amp rating of breaker
