Well packed, shrink wrapped to protect against moisture, arrives inside box shipped in padded bag. Device fits standard size rail, screw terminals are smooth. L&N for 4mm² cable use a smaller screwdriver than E/Ground 6mm² which needs one size larger. It would be better for installers to use the same screwdriver for everything. Should be protected with 32A mcb next to main switch.

I can’t say if it works well because I’ll have to wait
To an overvoltage in the network.
Comes without instructions so you have to know how to connect it.
According to my electrician it has to be placed before the differential
Connect the neutral and phase up and down to the ground terminal.
It is assumed that if there is overvoltage the drift to the ground protecting the frame.
I recommend the seller
