I am working on an Arduino project that includes the use of remotely operated breakers that have 3 pin connectors on the end of 6 inch pigtails. I have inserted a picture below. I need the connector that the below plug will be connected to. It needs to be a PCB type connector as I am designing a PCB board for 15 of them. I have spent the last 2 days searching the net for its counterpart with no luck. It may be a proprietary type, but not sure. I guess if all else fails I will need to remove the connector and use 3 pin screw type connectors, which are not as sturdy as the existing 3 pin connector.
