Hello , i'am facing a screw compressor breaker issue , lately a lot of power interuption hapens and the breaker trips when it hapens , but now the breaker don't even work, i mesured the same phase in two points of the breaker output, its 3 ph + N 630A MPCB but we only use the 3 phases output, its runing a 250 Kw compressor AC motor in Delta/star, here is the MPCB parameters set in the attachments, i checked the compressor circuit and motor and it doesn't look like there is a problem in it, so are those interuptions the reason for those MPCBs keep failing , and if yes can you explain why ? thank you
