As above,I do work for a fabricator of hot food counters and they need a 3ph db to fit in a cupboard about 500wide x 300high.I have found a proteus unit,but would prefere another brand.In the past a din rail box has been used with mcb,s hard wired to a main switch,but I believe there is no warranty with such a unit.Thanks for any help.
