Motor contactor with electronic overload relay

[strawburner]

I am somewhat new to the latest technology in motor controls. I have a customer that has a metal shear that was converted from 480 volt to 240 volt 3 phase. It pulls about 9 amps and now the electronic overload relay does not dial up high enough for the FLA of the motor on the lower voltage. Somewhere I thought I seen a motor start contactor with a electronic overload relay that is DIN rail mounted and it was quite small and compact and I think it was all one unit by that I mean I don't think you could detach the overload relay from the contactor itself. Possibly made by Schneider Electric. My control box on the machine is kind of small and I did not really want to go with a typical motor starter with the heater overloads. Does anybody have some suggestions on what would be the most economical or some links to a product that I could use. Thanks

You are looking for an IEC contactor. The contactor and overloads are separate even though it looks like they are one piece.

Any decent supply house should be able to help you out.

Is the contactor part of the starter rated for the motor hp at 240 volts?

Good point I need to check that out

Thanks for the help! I am looking forward to getting this unit up and running.
