I've got a project underway with six motors on AB SMC-3 soft starters. Generally I have used HMCP type breakers (magnetic only breakers with an adjustable trip point) on motors in the past, but I'm looking at the quote and comparing it to the price of non-adjsutable thermal-mag moulded case breakers and asking myself "why would I spend this extra money?" It adds up in a panel with six motors. (about 3-1/2 times as much).
So what real advantage do I gain, especially since I'm using soft-starters?
