PA0PBZ,
thanks for posting that picture with the cover removed.
Have they painted the fuse surface in white color or is it really one of the better fuses?
The truth is hidden deeply in their service manual:
[...
1. Fuse
The DM3068 has three types of fuse, which are: power fuse, current input fuse
on the rear panel and internal current input fuse on the mainboard, the
parameters are as follows:
115V Power fuse: AC, 250V, T250mA, slow- melt, 5x20mm
230V Power fuse: AC, 250V, T125mA, slow- melt, 5x20mm
Replaceable 200mA current input fuse on the rear panel: AC, 250V, F500mA,
quick-melt, 5x20mm
Internal 10A current input fuse on the mainboard: AC, 250V, F10A, quick-melt,
6x32mm...]
I just looked up some parts from my ESKA catalogue to have an idea how much protection is available for a fuse sized 6,3mmx30mm (10A current input)
632.128 FF 12,5A 500V 1.500A
632.528 F12,5A 500V 1.000A
632.028 F12,5A 250V 1.000A
There are higher extinguishing currents available but they are rated below 250V.
This is far away from that 30kA extinquishing ability of HRC? fuses.
Anyway, even if the current fuse setup may comply with today's regulations I would have expected better ones.
Most probably the three bags correspond to mains 125V, mains 250V and 200mA current input.
