Electrical Life — AC-1, AC-2, AC-3 and AC-4 Utilization Categories
Table 34-280. Utilization Categories
Life Load Curves — Eaton’s Cutler-
Hammer IT. Electro-Mechanical Series
IEC contactors have been designed
and manufactured for superior life
performance. All testing has been
based on requirements as found in IEC
60947-4-1 and conducted by us. When
selecting a contactor designed to IEC
requirements, the specifier must give
attention to the specific load, utiliza-
tion category and the required electri-
cal life. For a definition of Utilization
Categories, see Table 34-280 above.
Figure 34-148. Electrical Life — AC-3 Utilization Category
Figure 34-149. Electrical Life — AC-4 Utilization Category
CA08102001E
The International Electrotechnical Commission (IEC) has developed utilization categories for contactors and auxiliary contacts. The categories describe the
type of electrical load and the conditions for making and breaking the current.
Category
AC-1
AC-2
AC-3

Note: Preliminary data.
Plugging is stopping or reversing the motor rapidly by reversing the connections while the motor is running.
Inching or jogging is energizing the motor once or repeatedly for short durations to obtain small movements of the motor driven load.

Typical Application
Non-inductive or slightly inductive loads: Resistance furnaces, heating.
Slip-ring motors: Starting and stopping of running motors
Squirrel cage motors: Starting, switching off motors during running (motors in most industrial applications typically fall into this cate-
gory).
Squirrel cage motors: Starting, plugging , inching

Note: AC-3 tests are conducted at rated
device currents and AC-4 tests are con-
ducted at six-times rated device currents.
All tests have been run at 460V, 60 Hz.
Actual application life may vary,
depending on environmental condi-
tions and application duty cycle.

Decide what utilization category the
application is and choose the
appropriate curve from Figure 34-
148 or Figure 34-149.
Locate the intersection of the life-
load curve with the operational cur-
rent (le) of the application, as found
on the horizontal axis.
Read the estimated contact life
along the vertical axis in number of
operations.
