I'm wondering if somebody has mixed up the voltage levels and it's really a straight 4-wire wye system at 230/400 or thereabouts. The 440 designation was the standard specified level for the highest nominal voltage system in the U.K. before standardization: 250/440V.
Or the 440V is the US 480V system...
