Nice bit of kit - to use where the Prospective fault current exceeds the
breaking limit of MCBs.

Quite handy when you want working discrimination between head end of a
submain and a downstream MCB but can't afford the have the two steps in
trip rating that would be required to achieve it reliably with cascaded
MCBs as well.
