The trip unit of a circuit breaker measures the amount of current and calculates its effect on the system against its settings, and will trip or open the breaker as required. The larger the current measured, the quicker the breaker should trip or open.

To ensure that the trip unit, its settings or factory parameters, and associated components are working properly a secondary injection test set can be connected to the unit for analysis.

Eaton Cutler Hammer-140D481G03The 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 Secondary Injection Test Set 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 shows that the solid-state trip unit is not functioning properly, the trip unit should be replaced.
