At the moment, there is no such a limit. Auto bidding will send bids to all job posts that were found by scanners during the day, unless of course there are errors due to an internal failure or perhaps that you are low on connects.

To avoid the situation of sending bids to jobs that are irrelevant to you, we recommend that you segment your scanners. The more a scanner is segmented, the lesser jobs it will detect per month. This prevents the scanner from spamming the platform with copying and pasting the same cover letter for multiple job posts. For more information, see 🙅🏻‍♀️ 300 jobs / month limitation.
