Hi,

Does anybody know why the fuse diagram for the w213 specifies the following?

CAUTION: On fuses 400-484 use only fuses with add. of letter "S" according to MBN 10153-2

Searching the internet I am not finding any fuses with S on them. What does it mean and in what way are they different to fuses without S ?
 
The "S" is for "slow acting"...I think the MB fuses are silver plated to help prevent electrolysis. A slow blow fuse is different from a fast acting fuse in its capability to withstand transient pulse currents...it can withstand the surge current upon power-on/off, ensuring the equipment works normally.

Thank you! Now I find a lot about Slow acting fuses.

S ?

Surely if you use fuses with no letter “S” They would be “fue”?
