Trying to find replacement contactor & modules.

[M107]

I have been handed a contactor by my brother in-law who works on farm dryers/conveyors & one of his farmer customers removed this asking if it can be replaced. He has kindly brought it to me:| :shakehead & asked if I could replace it. All I know about it's use is it is used to run socket outlets in a workshop that can be turned off by a key switch & I assume E stops.

I freely admit I rarely work with contactors & auxilary modules so due to the age of the unit, I have a question for our longer serving members in the trade..... about one of the removable modules on the side.

I've been told by Eaton this module is a rectifier.

This module (under the clear plastic)I wanted to know if anybody had a part number/name for....Eaton tec line said it was the coil A1 & A2 terminals.

(as I always say to others put your thoughts first & others will help so....) I think it is for the use of E stop/key reset, as it has no function until the contactor itself is energised & the auxilary contact terminals are closed or opened?

Any pointers on a replacement?

Thanks.............now I'm off to trwal google for part numbers..

Well it's certainly an old contactor.

I think the circuit board on the side is a crude rectfier / dropper resistor, to allow a lower voltage dc contactor coil to operate directly from 240v.

Personally I would just replace with a new contactor with 240v ac coil.

Thats what I said Dave "just replace with a new unit".......however curiosity got the better of me hence the questions....

I have found the Eaton part numbers for their Autoline units for anybody who requires such a beast in the future:

4 pole with rectifier 428ALCFPR

4 pole without rectifir 428ALCFP

Side mount Aux contacts 8TA8DN11
