Davids board is at https://www.audiovisualdevices.com.au/viewprod.php?catid=&productid=APC731
Mine in at http://www.hansonelectronics.com.au/product/hexfuse/
Both of them are 3 input and 6 output. If the fuse is blown or not inserted then the led will light up.
The current rating, fuse type and physical size are about the only differences between the 2 of them. The advantage of 3 in and 6 out is that it allows multiple power supplies on the 1 board or handle greater current. The 1 in the video has 1 30A input connector which means that the 6 outputs can only total 30A. My hexfuse for instance has 3 30A inputs and 6 15A fused outputs.
