I chose for myself Eaton/Memshield 'cos it's built like a battleship, and indeed wouldn't look out of place in one. The availability and cost of three-phase RCBOs were a consideration. Schneider and Hager were on the shortlist.
The Hager's do look very nice! ? How did the availability/price of RCBOs compare? Cheers.

I don't think that there was a big difference in price of the three-phase RCBOs from Eaton or Schneider - both were eye-wateringly expensive. IIRC, the Schneider ones take up more space. I don't know whether the changes to 411.3.3 have led to greater numbers of sales and a consequent fall in price. Perhaps there are just more documented risk assessments now? ?
Out of interest, would you say that a RCD or RCBO would be essential when installing a 20A 3-phase Socket in a small (sole-trader) commercial premises?

I thought that it was important enough to spend a few hundred pounds on one. The thing is that machine tools have a lot of exposed conductive parts.
The obvious workaround is to hard wire the equipment. Another alternative would have been to have a (much cheaper) RCD incomer, but I wanted to avoid the possibility of everything going off at the same time.
