I have a 100/20 MTTP with two Victron 200w 24v panels connected in series.
Would a circuit breaker like below be suitable to go between the panels and MTTP, as I notice the breaker is only rated for 65v (and the MTTP can take 100 max)?

It seems ok as far as I could see in this link

Up to ~60V or so (per pole), I use Schneider iC60H or iC60N series. So, for a 100V MPPT a double pole breaker would be ok. Hager MJT series is also suitable for that voltage range acording to manufacturer. These two brands are readily available in Europe and I consider them good options up to ~63A (125A for iC60H). These breakers are also not polarised, which is a plus.
For higher voltages I can only find polarised breakers available in Europe. We could also continue to use iC60H/N or MJT, but just with more poles in series, for example, use a 4-pole breaker, 2 in series for positive and 2 in series for negative.
Ah I see. I could split the voltage across two (or more) poles. Now the single throw, multiple pole circuit breakers make allot more sense. Thanks for the explanation.
I wanted to combine switching function and circuit protection in a single unit to save on space and weight, but I think I'll use a separate switch and fuse for the panels.
Thanks again.
