Air circuit-breakers of large current ratings, complying with IEC 60947-2, are generally used in the main switch board and provide protector for currents from 630 A to 6300 A, typically.(see Figure H26).
Testing a circuit breaker is simplicity itself – the test set is a personal computer or tablet pc running the CBAnalyzer Windows software program and an accelerometer magnetically mounted to the front of the breaker being tested.

How are the primary and secondary injection tests

Removing the interrupter from the circuit breaker to obtain more reliable test results introduces more opportunities for the tube to be damaged and the final condition of the reinstalled interrupter would not be measured. The risks tend to outweigh the benefits in this case. Powell has received interrupters from customer breakers that were tested with the field version of the Magnetron tester
