Now NFPA20 allows use of MV contactors for fire pump motor control. But, there is no mention of requirement that the contactor shall be latched type or atleast that the running motor shall not trip on short time power system voltage dips. Any comment!
Just to let you know, I also posted a similar query in NFPA codes forum and awaiting responses.
