That's because it needs be 4 terminals: Live Neutral Earth and Switched-Live.

Fuse-blowing is commonly due to mistaking the switch cable for one of the loops and connecting red and black to L and N. When the switch is turned on that places a dead short between L and N.
Connect all 3 reds to a bit of insulated choc-block - this is L Connect the black from the switch to the L terminal on the light - this is switched-live Connect the other 2 blacks to the N terminal on the light - this is switched-live Connect all the earths to the E on the light (with green/yellow sleeving)
