DC Circuit Breakers

Recommended Posts

My installation manual recommend a 60A DC circuit breaker between PV and MPPT.

Where can I buy a true DC breaker as I understand this is not the same as a AC breaker?

I'll tell you what I do. I don't have a breaker there. I have one of these fuse holder disconnects which doubles as a breaker. My PV current is max 8 amps (one string per mppt), the short circuit current (Imax) on the panels, so I certainly don't need a massive breaker for this.

I have some 63amp DC zjbeny's somewhere. I'm sure I could scratch up up for you. Otherwise some fuse holders and fuse links will work

Hi

I have a similar one of these that I think I got @ Rubicon.  Its sits near my inverter.  I also have a PV cutoff switch (rotary) next to my pvcombiner box.168489-c60h-dc-1p.jpg.e5b59c80137862aea6806aa79d9709eb.jpg

Did you order from China directly?

Could you post the link?

No just from a local supplier to see what it's like.

 

 

Could you share the supplier? I couldn't find any local (except one which, I know, they have nothing) on Google

Contact the distributor MCE Electric and ask about supplier in your area;

Pta 012-804-6005

DBN 031-569-4846

Cape Town - no luck, but you've still got the mountain:lol:

Thanks all for the feedback and help. I found one at ACDC in Strand ( Cape Town ) They also have Fuse holders.
 

I found the quality on the AC DC change over wanting. The terminals strip and buckle
