When it’s necessary to test circuit breakers and protective relay systems, a secondary injection test set is the main piece of electrical test equipment companies utilize. 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.READ MORE >>

Secondary current injection testing is performed on solid-state trip units using a specially designed power supply unit. However, the secondary injection method only tests the solid-state trip unit, and does not test the current sensors, wiring, or the breaker current handling components.READ MORE >>
The ABB Ekip Connect Secondary Injection Test Set is a software application for personal computers that interfaces with ABB low voltage circuit-breakers equipped with compatible protection releases.
The test set allows the releases to be configured, monitored, controlled and tested. Ekip Connect can connect to the releases in the point-to-point or network modes, and connection is made using the front test connector or to communication modules installed on the circuit-breaker.READ MORE >>
Now available for rent from Protec, the GE M-PRO Test Box, is a must have when testing the health and configuration of the GE M-PACT Plus Air Circuit Breaker.
The GE M-PRO Test Box is used as a means of powering up an M-PRO Plus Protection Relay - Electronic Trip Unit, simulating faults by secondary injection or for performing a forced trip of the breaker.
M-PACT Plus breaker will be in the test mode while M-PRO Plus is connected to the Test Box through the test connector.
Connect the Test Box to the M-PRO Plus via the front panel 26-pin connector using a 15-pin to 26-pin converter.
Do not test the M-PRO Plus with the charger still connected, as this will disable power to the M-PRO Plus.
The GE M-PRO Test Box may be used as a simple power box to facilitate viewing of faults (e.g. after a trip) or the
history of trips.
When testing and verifying the pickup levels and time delay settings of Amptector, Digitrip, RMS or Optim trip units. the Eaton Cutler Hammer 140D481G03 Secondary Injection Test Set is used. However, in the past the Eaton Cutler Hammer 8779C02G03 DS / DS II Adaptor, the Eaton Cutler Hammer 8779C02G04 Magnum Adaptor and the Eaton Cutler Hammer PRTAAPM Auxiliary Power Module have been in short supply and not easily available.READ MORE >>
