Blue Smart IP22 Charger 12v 30A UK Plug Fuse

Hi - I have a Blue Smart IP22 Charger 12v 30A charger hooked up to 3 95aH AGM batteries in parallel. This has been used on shore power without issue to charge batteries from around 95% to 100% without issue, however when I've used this at home to charge from 85% it seems to have blown the 5amp fuse in the UK plug, has anyone else had issues with this, or can suggest any reasons why it would be blowing this fuse? To me it seems like 5amp for this fuse is small on a 30amp charger but I'm trusting it's right as that's what came from the supplier? Thanks!

A 5A fuse is more than adequate and would be selected for the mains cable size.
At full chat, that charger would be taking less than 400W from the mains which would be in the region of 1.8A.

If you replace the fuse and it blows again, then there is surely a fault.
