Count On Square D by Schneider UTS-3 For All Your Secondary Injection Testing Needs

Square D by Schneider UTS-3 Secondary Injection Test SetA secondary injection test is performed using a specially designed power supply unit, such as the Square D by Schneider UTS-3 Secondary Injection Test Set.  The secondary injection test method only tests the solid-state trip unit logic and does not test the current sensors, wiring, or the breaker current handling components. Most solid-state trip units have terminal blocks that are equipped with test plug terminals for making the calibration test. The test set allows checking of the solid-state trip unit operation without using primary current. The Square D by Schneider UTS-3 Secondary Injection Test Set will pass enough current to check any desired calibration point. The breaker must be de-energized before checking the operation of the solid-state trip units. If the Square D by Schneider UTS-3 Secondary Injection Test Set shows that the solid-state trip unit is not functioning properly, the trip unit should be replaced.

The Square D by Schneider UTS-3 Secondary Injection Test Set is designed to perform operational tests and diagnoses of Square D by Schneider electronic trip circuit breakers, circuit breaker components and tripping functions.
