Hi
I am looking at DIN Rail mount enclorures...
Why are theese so $$$$ expensive!?

I can buy a resettable fuse in that encapsulation for 14 SEK ex VAT (approx 2 USD ) already in multiples of one, but for an empty enclosure i must pay more than the double each  - about 30 SEK - when I buy at least 30 pcs?

So, it is even economical to buy fuses, dissassemble and throw the internals out! - even at good work hour pay that is cheaper - that is just crazy!  But it does not look professional...

I see lots of different DIN rail mount devices, so i thought there should be competing enclosure manufacturers too.
And thera are a some, but they sell at ridiculous high cost all of them.

I thought maybe I cold buy shells of that fuse cheaper than the fuse, but their rep would not care to ask the manufacturer for less than thousands of units.

The size I need is about the size of a fuse, with four terminals for mains voltage and four for signal sida.  (I am designing a intelligent relay, probably with a PIC in it)  So like 10 to 17 mm long (along the rail), 65 mm high, 80mm wide.  I can go with somewhat smaller too.  Preferrably ventilated, i will have an expected total power loss of upp to 5W in a future model.

In an earlier design I used a screw terminal, and integrated the electronics inside, making it just 6mm wide.  But that is too small for the current design.
Even using double such shells is too small, plus clumsy to build, and screw terminals that are big inside (2 and 3 level types) aint very cheap anyway...

Other ideas: 
Small box + rail foot.  Bad: Can not find a good rail foot at good price.

Any ideas?
Volume is probably about 100 per year.
