Applications Summary
Utilization Categories
Utilization categories are used to describe the type of motor load and duty cycle. Each category has a unique life/load curve which is
used to estimate expected electrical life of a specific controller.
Following are descriptions of the most common AC utilization categories:

Life Curves . . . how to use
To determine estimated electrical life for a specific contactor, follow these guidelines:
1. Determine appropriate utilization category. The illustrations below show typical life curves for C-2000 contactors which will operate
2. Once the appropriate utilization category has been determined, then using the appropriate curve, it is easy to determine the expect-
Example: Using a motor duty cycle of starting and stopping (standard) for a three-phase squirrel cage motor rated 15 horsepower at
A. Locate rated operating current on bottom (horizontal) scale and draw a vertical line to intersect the first heavy line which will indi-
B. Reading the vertical scale to the left of the intersection point denoted an expected life of approximately 3 million operations for the
C. If greater contactor life is required, continue the drawn vertical line to intersect with a larger size contactor line.
Caution note: Do not apply a contactor for use on a motor which has greater horsepower rating than shown in the tables on pages 2-20.

Noninductive or slightly inductive loads, such as resistance furnaces.
Starting of slip ring motors without plugging.
Starting and stopping of squirrel cage motors. This utilization category is typical of the standard type of
motor duty encountered in most industrial applications.
Starting of squirrel cage motors in continuous inching, plugging, and reversing applications.
