0.4 Mpa opening and closing
0.4-------------Closing and opening
When the SF6 gas pressure inside the SF6 circuit breaker falls below (0.4) Mpa, the signal circuit sends an interlock signal; at this point, it is prohibited to perform any operations on the circuit breaker (such as opening or closing it).
When the SF6 gas pressure inside the SF6 circuit breaker falls below (0.4) Mpa, the signal circuit sends an interlock signal, and operation of the circuit breaker (opening or closing) is prohibited at this time.
