T means Slow blow , 6.3A is the maximum current this fuse will conduct , any more and the fuse will heat up and melt the conductor .

Maximum voltage capacity is 250V , this means the maximum voltage that the fuse can block from "jumping" . It means you can use it in a system from 0 - 250V with a maximum current handle of 6.3A .
