Thanks Jaco but I ended up finding something. Fuse links and disconnector cost me around R1700 all in. Now the question is, is this a case of “goedkoop koop is duur koop” or will I be ok?
I have very little experience with Swan’s products and am a bit weary but the guy at the shop promised me there won’t be contact resistance/running hot problems, it is DC rated and all the big installers buy these from them.
I ended up going for a 250A seeing as I don’t typically run at more than max 170-180A. The 300A rating was just because the Multiplus II 8kVA manual recommends a 300A fuse for that 15kVA short burst peak capability and the Freedom Won 10/8 has a continuous/peak current rating of 200A/300A on its pre-fitted 50mm cables (only 1 per neg 1 per pos). With the loads I run I am yet to see such peaks.
It is mostly just for a disconnect and perhaps overcurrent redundancy on both pos/neg to remain compliant seeing as the FW already has a built-in breaker.
If I may, 2 questions:
Do you know what this greasy substance is they put on the contacts, it seems almost like soldering flux or DC4 insulating grease? I don’t see why they would use an insulating grease as it could increase contact resistance if it doesn’t burn off quickly? Did a spot check with multimeter and it is not conductive.
Hi @mmaritz , just a baby Freedom Won, please refer to my reply to Jaco for details. 1x50mm cables initially seemed small to me too but the specs are what they are on the Freedom Won and it came pre-fitted with these cables, manual states 200A/300A continuous/peak current rating.
You should be fine with this. Keto is very expensive compared to Swan and Chint, but I quoted you on the keto as per your first post. We also sell Chint and Swan, and the price you paid is market related.
