Max Volts 264   Max Amps 62.5  1.5KVA

The current rating does not make sense. How can I sort this out ??

As Carl said: Move the decimal point in the current rating. It's very common to see Chinese products with such nonsensical ratings, due to typing error - or at least that's what they say it is.

240V at 6.25A is 1.5kVA. That's probably the nominal rating of the transformer.

The typical way to interpret a rating of 264V 6.25A 1.5kVA is that none of those limits shall be exceeded. All combinations that result in none of the three ratings exceeded is fine. So, at 264V the current rating drops to 5.68A.
