6. Power frequency withstand voltage: The circuit breaker shall meet the withstand voltage test of AC 50Hz and 2500V for 1min. The conventional experiment is 1s without flashover and breakdown.
7. Mechanical and electrical performance:
The number of operation cycles of the circuit breaker is 10,000, of which the number of loaded operation cycles is 1500 and the number of no-load operation cycles is 8,500.
