Circuit Breaker - Secondary Current Injection Test Sets

Circuit protection is a critical factor in any electrical system. For safety and security it is essential that all protection devices are tested effectively. Testing circuit breakers at their full operating voltages and currents (primary testing) can be impractical and unnecessary. In this situation secondary current injection testing is performed.

Secondary injection testing is normally conducted when the circuit breaker is closed but is not carrying any current through its main poles. It involves connection of the circuit breaker to a test set that can inject and measure the current required in the device relay to cause it to operate.

Electro Rent provides a full range of secondary current injection test equipment from manufacturers including ABB, Eaton/Cutler Hammer, General Electric, Siemens, Square D/Schneider and others.

With Electro Rent’s flexible acquisition options you can rent, lease or purchase secondary current injection testers to meet your short and long-term needs.
