Because of the overload in the MCC an overcurrent has happend which thereafter resulted that break switch of the transformer (in the field) has been disconnected first but not the load break switch form from the MCC (type NZM3, 630A).
The load break switch in the MCC was demaged because of this problem.
Here, we are see a missing service from your side, which could result to more greater damage in our plant.
Now, the load break switch of the MCC has burn-ups marks on L2, L3 so that the functionality is any not more provided. Please see the photos in the attachments.
Please send us another MCC - load break switch, as soon as possible in the exchange for the demaged one,
We ask for exchange and validation of the demaged MCC - load break switch as quickly as possible, to avoid an unnecessary interruption and operation of our production plant.
