Power supply - 48v DC 20amps
Drives - steppers 1400oz 4.6 amps
Drivers - Gecko 201x

Are you using the contactor as an Estop Contactor?
You will want a contactor with DC voltage contact ratings. I would run both the DC- and the DC+ across a contact.
Eaton Moeller DIL or XTC series contactors are good, Schneider Telemecanique LC1DT series, etc....
20Amp contact rating would be fine.
Just remember to look at the coil voltage you intend to use. I would recommend 24VDC....

Hope that helps
Marty

I would like to use this as an estop contactor to shut down the spindle and steppers but leave acorn running, so that I can resume a program. Thanks

Look at the Acorn SYSTEM schematic in the Acorn Schematic set. It shows what you are wanting to accomplish

Would something like this work.

Yes. Same one Centroid uses and sells other than it's 24vdc

Thank you. Would you also recommend the Quencharc?
