Tanks oldfieldguy for your answer. We realy check the conections leads and put it near the botles for remove any conections in the way. We found in another breaker's manual, that had limits for change botles in case of contacts wear out. But they didn't said the value. Do you have any idea about...
We worked recently in old Toshiba vacuum breakers (1982) and we find very high contact-resistance (2000 microohms).
Somebody knows the life of this botles?
