Hello SV Demeter,
Sorry for my late reply, I didn't notice your answer/question
I found this ETA circuit braker in som local electric
resellers but the price
was very expansive (more than 200 € + shipment). And as far as I can see, this product is very low quality for marine
However , Radiospares (and some other online resellers) can sell this product if you wish to use the same one.
I changed my mind and I installed an ANL fuse....
