Circuit Breaker | Secondary Current Injection Test Equipment


Easily Maintain All Circuit Protection Devices


To keep electrical systems running at peak performance, you need functioning circuit protection. Use current injection test equipment for regular testing that doesn’t force circuit breakers to operate at full voltages and currents.


Using test equipment for secondary injection testing, technicians can analyze electrical protection systems when circuit breakers are closed, but not carrying current through its main poles. This type of testing involves the connection of the circuit breaker to a test set that can inject and measure required currents needed to operate for a safer method that ensures all protection devices are operating at the peak.
