Bulletin Line Load-Life Curves Bulletin Line contactors and starters are designed to provide superior performance in a variety of applications. These load-life curves are based on Rockwell Automation tests according to the requirements defined in IEC -. Actual contact life may vary based on the application, duty cycle, and environmental conditions from that indicated by the curves. To find the contactor s estimated electrical life, follow these guidelines: Choose the appropriate graph that most closely approximates the utilization category of the application. Locate the intersection of the life-load curve of the appropriate contactor with the application s operational current (I e ) found on the horizontal axis. Read the estimated contact life in millions of operations along the vertical axis. Contact Life for Mixed Utilization Categories AC and AC In many applications, the utilization category cannot be defined as either purely AC or AC. In those applications, the electrical life of the contactor can be estimated from the following equation: L = mixed L AC L AC AC + P ( ) L AC Where: L mixed = Approximate contact life for a mixed AC/AC utilization category application L AC = Approximate contact life in operations for AC utilization category (from AC life-load curves below) L AC = Approximate contact life in operations for AC utilization category (from AC life-load curves below) P AC = Percentage of AC operations Utilization Categories CategoryTypical Duty ACStarting of squirrel cage motors and switching off only after the motor is up to speed.

Bulletin Line Full Load Currents of -Phase, Hertz AC Induction Motors The full load currents listed below are average values for horsepower rated motors of several manufacturers at the more common rated voltages and speeds. These average values, along with the similar values listed in the U. S. National Electrical Code (NEC), should be used only as a guide for selecting suitable components for the Motor Branch Circuit. The rated full load current, shown on the motor nameplate, may vary considerably from the listed value depending on the specific motor design. ATTENTION: The motor nameplate full load current should always be used in determining the rating of the devices used for Motor Running Overcurrent Protection.
