I've found the MEM excel and Glasgow units to have gone downhill terribly these days, the last ones I had new had poor quality terminals.
That's why I've moved over the the schneider/square D stuff.
Well now RS is reporting the MEM "Glasgow" switch (part 726-4740) is made in India. Now there are some
very smart and competent Indian engineers out there, but when production is moved it is only ever to do with cost-saving, and that is invariable related to quality cutting.
Had a look at the Square D SQB1003K and it looks the part, I really like how the terminal shield goes to the front/bottom so if you drop the nuts, fuse, etc, when changing a blown fuse you don't end up with them rattling around your still-live busbar chamber!

A fused switch has the movable fuse carriage which completely withdraws the fuses.
A switch fuse has a switch with fuses installed after the switch.
I would avoid proteus due to their terrible reputation.
I prefer schneider switchgear these days, they do two ranges which are the exact same kit painted different colours, and priced quite dufferently.
Craig and Derricot are also a very good brand of switchgear I occasionally use.
The terminology is not very well used, for example Hager list various definitions then go on to describe their own kit with different names!
Had a look at Craig & Derricott Ltd and it is a good suggestion, I like the possibility of getting custom aspects (e.g. sensing switch settings via aux contacts, etc) but remains to be seen if there is a budget for that. Also, as for many suppliers, they are clear as mud in terms of what you actually get!
Interior photos? Missing.
Data sheet giving the exact switching arrangements? Missing.
