A secondary injection test set helps in finding faults in circuit breakers by simulating the operating and overloaded conditions of the circuit breaker. This test is safer on circuit interrupters because the protective device is disconnected from the power line. This reduces damage caused by inductive kickback generated when it interrupts large currents.
Assessing protective devices for signs of degradation ensures its continuous and safe operation. Faulty interrupters can trip even if the current is within acceptable limits. It can cause intermittent power especially if it trips repeatedly. A circuit breaker test set helps determine if the circuit breaker is within its normal operating limits..
The Square D by Schneider UTS-3 Secondary Injection Test Set is designed to perform operational tests and diagnoses of Square D electronic trip circuit breakers, circuit breaker components and tripping functions.
