These appear to be standard Stake-on spade connectors, AMP among others can supply.
Although if the intention is to attach a conductor for remote breaker use etc, to avoid searching for the printed circuit type, I would be tempted to solder the conductor directly to the board and terminate at the breaker end.
You would have to solder the connector in anyway.
