Contactor Selection for Utilization Category AC-3
How to Use the Electrical Life Curves
The contactor electrical life curves on the following pages may be used to estimate the number of make
and break operations a contactor can achieve for a specific application. Compare the application to the
utilization category definitions listed on page 16 and select the appropriate chart. Each chart shows the
Number of Operations in Millions on the Y axis and the Current Broken in Amps on the X axis.
AC-1 The current broken should be the same as the make and maintain current.
AC-3 The current broken should be the same as the full load current rating (FLA) of the motor.
AC-4 The current broken should be the same as the locked rotor current (LRA) or
Once the appropriate chart is selected, find the breaking current of the application on the X axis of the
chart and draw a vertical line. Draw a vertical line at this point. Find the intersection of this vertical line
and the life curve of a particular contactor. At the intersection point read the number of electrical
operations off the Y axis. If longer electrical life is required, continue checking the intersection points
until an acceptable contactor is found.
