We have 4 unit of this Circuit breaker 2500 A , it is connected with Generators " 4 units " . since 1 week we got the 4 units broken, the Breaker broken at open position, and lever operating the gear set not latching and charging the gear to close the breaker.
We are looking for a drawing showing to us how to disassemble the breaker , then we can reach charging mecahnizim " mechanical set of gears , latch and levers " , we might be able to fix the breaker since the cost of replacement is 5,000 USD.
Regards;
Tarek
