Square D by Schneider S33595, a Full Function Secondary Injection Test Kit

Secondary injection testing normally involves disconnection of the protective device from its normal VT/CT and connection to a specialist test set that can inject and measure/record the required operating signal directly into the protective device relay to cause it to operate the circuit breaker. The advantage of secondary injection testing is that the circuit breaker does not have to interrupt large current and only low voltage signals are injected to operate the device.
