Bogdan, Seems to me I saw that type of fuseholder once a long time ago. Can't recall where and don't know whatever happened to it.
As for me, I just use 5x20 mm fuses everywhere. I provide spares in spares kits to field service types. As we ship world wide, we stopped having problems once we switched and included them in the spares kits.

This gave me a crazy idea, which could reduce the cost of compliance, namely mount the fuseholders in a fashion where the footprints of the fuses would cross, i.e. either one could be placed in the proper holder, but not both at the same time. Is this idea worthy of being patented? Bogdan.

However, either can be used and either will protect if used correctly. UL does "Recognize" some brands of European-style fuses. Check with your test house(s) to see what they'll accept. The potential problem is availability of replacement fuses: American fuses are not widely available in Europe, and 5x20 mm fuses are scarce in the US. Worse, there are some 5x20 mm fuses in America built to UL/CSA fuse curves; somebody's bad idea. ---------- From: Rick Busche To: [email protected] Subject: Concerning Fuses List-Post: [email protected] Date: Monday, October 20, 1997 6:46AM I have a product which uses clip-in fuses on the primary side of a power supply card. In order for this supply to be used in the US and European markets I am looking for a fuse solution compatible with all regulatory requirements. It is my understanding that UL/CSA require different performance characteristics than found in the 5mm European styles. 1. Can US fuses be used to meet the regularly requirement of Europe? 2. Are 5mm fuses REQUIRED to meet world wide applications? If so must they also be used in secondary circuits? 3. It has been suggested that both fuses could be put in series. Is this a solution? Thanks in advance...
