(1) Service-Limit Current Ratings -- The service-limit current ratings that are 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 that are used shall not exceed the service-limit current rating of the controller.

(2) Plugging or Jogging Service -- The listed horsepower ratings are recommended for those applications requiring repeated interruption of stalled motor current that is 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.

(3) If maximum available current (at capacitor terminals) is greater than 3000 A, contact your local Rockwell Automation sales office, Allen-Bradley distributor, or NEMA ICS-2 Standard.
