⋆ Service-Limit Current Ratings — The service-limit current ratings shown represent the maximum rms current, in amperes, which the controller shall be permitted to carry for protracted periods in normal service. At service-limit current ratings, temperature rises shall be permitted to exceed those obtained by testing the controller at its continuous current rating. The current rating of overload relays or the trip current of other motor protective devices used shall not exceed the service-limit current rating of the controller.
‡ Plugging or Jogging Service — The listed horsepower ratings are recommended for those applications requiring repeated interruption of stalled motor current encountered in rapid motor reversal in excess of five openings or closings per minute and shall not be more than ten in a ten minute period.
§ If maximum available current (at capacitor terminals) is greater than 3000 A, please contact your local Rockwell Automation sales office, Allen-Bradley distributor, or NEMA ICS-2 Standard.

Load-Life Curves

Bulletin 500 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 947-4. 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 AC3 and AC4

In many applications, the utilization category cannot be defined as either purely AC3 or AC4. In those applications, the electrical life of the contactor can be estimated from the following equation:



Where:

L_mixed = Approximate contact life for a mixed AC3/AC4 utilization category application

L_AC3 = Approximate contact life in operations for AC3 utilization category (from AC3 life-load curves below)

L_AC4 = Approximate contact life in operations for AC4 utilization category (from AC4 life-load curves below)

P_AC4 = Percentage of AC4 operations

Utilization Categories

Category Typical Duty

AC3 Starting of squirrel cage motors and switching off only after the motor is up to speed.

AC4 Starting of squirrel cage motors with inching and plugging duty.
