EM24: 250mA fuse for neutral connection

Hello,

for a planned grid-connected PV system with a MultiPlus 2 I am about to install the EM24 Ethernet after the official energy meter.

Now I just found in the EM24 manual, that a 250mA fuse is necessary in the connection to the neutral wire.

I found almost no information about this fuse? What kind of fuse do you normally use that fits on a DIN rail with only 250mA?

Or does nobody use a fuse for the EM24?

Best regards David

Up to 8 attachments (including images) can be used with a maximum of 190.8 MiB each and 286.6 MiB total.

My sparky thought fusing the negative wire was very odd. We ended up with a 5amp fuse on the negative wire (din).
