Primary vs. Secondary Injection Testing for Circuit Breakers
Mar 14, 2017· Circuit breakers that have thermal-magnetic or electromechanical trip units can only be verified for correct functioning via the primary current injection test method. Circuit breakers equipped with solid-state trip devices can be tested using secondary current injection, which requires less time and expense to perform the test.
