Your Answer: Breaker needs to be marked bad and removed from service

Every breaker has lubrication in it, different parts get different lubrication and also varies by manufacturer. The question suggests that the breaker gets faster with each operation, so lubrication and exercise would be recommended. If a company wasn't qualified then they should send it for repair, where another company will lube and exercise it.

Spray lube on the bearings
Use penetrating lube on the bearings
