Assure Trip Units are Working Properly with the Eaton Cutler Hammer 140D481G03 Secondary Injection Test Set

  • Uncategorized

Secondary injection test sets are the main piece of electrical test equipment used to check circuit breaker and protective relay systems. Secondary injection testing differs from the standard primary injection testing method in that there is no current flowing and contacts remain closed during the testing process.

A trip unit 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.

By connecting a secondary injection test set you can ensure that the trip unit, its settings or factory parameters, and associated components are working properly.

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.
