Long-Time Delay, Short-Time Delay,
and Instantaneous Time-Current Curves
Curves apply at 50 to 60 Hertz and
from -20°C to 55°C Breaker ambient.
-20°C to 70°C trip unit ambient.
Settings Glossary
S or CT = Current Sensor Rating in amps
C or LT = Current Setting in amps
X or I
n
= Rating Plug Rating in amps
MicroVersaTrip Plus & PM Adjustments
Long-Time Function:
• Current settings (C): 0.5 to 1.1 in 0.05 increments
and are multiples of the rating plug amps (X).
Delay bands: 1, 2, 3, and 4
Short-Time Function
• Pickup settings: 1.5 to 9.0 in 0.5 increments
and are multiples of the current setting (C).
Delay bands (I

t In & Out): 1 = Min, 2 = Int, 3 = Max
Instantaneous Function:
• See table and curve above.
Power+ Adjustments
Long-Time Function:
• Current settings (C): 0.5, .6, .7, .8, .9, .95, 1, 1.1
and are multiples of the rating plug amps (X).
Delay bands: 1, 2, 3, and 4
Short-Time Function
• Pickup setting: 1.5, 2, 2.5, 3, 4, 5, 7, 9 and are
multiples of the current setting (C).
