Some info about Diazed/Neozed.
http://www.ad.siemens.com/et/beta/html_76/products/sicherungss.htm

Siemens seems to only specify Diazed for higher voltage applications thesedays.

Neozed's a lot neater, safer (from a shock hazard point of view) and ideal for 230/400V stuff.

Those minized switch-fuses are common in Ireland on modern consumer units as a 63A isolator.


There is a large range of Diazed and Neozed fuses available. Maybe one of our Scandinavian or German electricians who has used the system more recently might know what the curves/characteristics are?

This Korean site shows you some of the Diazed family quite clearly:
