Regular testing and maintenance of circuit breakers and relays is essential when dealing with sophisticated electrical systems.
Performance tests such as insulation resistance, contact resistance and electrical operational tests should be performed to verify that the circuit breaker is able to perform its basic functions.
The advantage of secondary injection testing is that the circuit breaker does not interrupt large amounts of current and only secondary, or low level signals are injected to operate the device.
The Square D by Schneider S33595 Secondary Injection Test Set is a full function test kit that is designed to perform tests on Micrologic, NT and STR Trip units.
Square D by Schneider UTS3 Secondary Injection Test Set is designed to perform operational tests to verify the proper functionality of
Square D electronic trip circuit breakers, and to diagnose issue when they do not operate properly.
