3 phase junction box

[chloebear]

Hi all,
Is there a 3 phase juncltin box commonly available?
I have a 3 phase board (small low useage) and would like to run 2x sub mains (single phase) from this supply - but would rather not come out via MCB's from the 3 phase board, would rather come off before the 3 phase board vai a junction and use 60A switch fuses for the protection of the new sub main cables.

any ideas????

Henley blocks ? but as it is 3 phase a decent adaptable box, din rail and Klippons IMO
