The Eaton Cutler Hammer 140D481G03 Secondary Injection Test Set is used to test and verify the pickup levels and time delay settings of a breaker’s trip unit. The Eaton Cutler Hammer 140D481G03 is also used to test Amptector, Digitrip, RMS or Optim trip units.
The Eaton Cutler Hammer 140D481G03 passes enough current to check any desired calibration point, allowing the solid-state trip unit operation to be checked without using primary current. The breaker must be de-energized before checking the operation of the solid-state trip units. If the Eaton Cutler Hammer 140D481G03 Secondary Injection Test Set shows that the solid-state trip unit is not functioning properly, the trip unit should be replaced.
