We have an old high speed circuit breaker protecting our 1000 kw dc motor having base voltage 700 and current 1750 ampere while the current rating of breaker is 3750 amperes (adjustable).The same breaker is around 40 years old and we suppose has almost outlived its life so considering this we purchased a new dc breaker with same capacity.Now my question is if we can use the old breaker with new one in the same circuit in series to have minimum spark during tripping? or should I put this in parallel?
