how much credit limit can be used ?

After payment u can use full cc limit again

Yes, you can use up to your full credit limit of ₹50,000 again without any penalty or issue

Credit Limit ₹50,000 

Used ₹47,000 on 19th July for an NCEMI
Paid ₹47,000 on 24th July to close that NCEMI

Since your available credit limit is restored to ₹50,000 after the NCEMI payment, you can utilize this amount as long as you stay within your credit limit

There should be no penalties for using the credit limit again, provided you don’t exceed it and make timely payments
