low cost sf6 circuit breaker device

To prevent a breaker being energized and suddenly tripping on dangerously low SF6 operating procedure requires varying healthy 6FS pressure to any breaker about to be re-energized or re-closed and as a last resort once a breaker reaches low-low the close coil (and possibly motor)will be disabled.
