Customer is trying to startup the 250hp SIZE 6 FVNR`s on both MCC`s and the LAL3640036M breaker is instantaneously tripping. It has been determined that the inrush current on the new 250hp motors is 5700 amps, which is much higher than what the rating of the LAL (adjustable trip range is 2000-4000 amps). <br /><br />In the Digest we list an LAL34400MC that looks like it will work. It is dimensionally the same and would use the same operating mechanism as the LAL3640036M

Yes, you could use the LAL34400MC breaker in place of the LAL3640036M.
