Are circuit breakers directional?

[Popga]

I just finished hooking up my ne Victron Orion DC to DC charger and noticed I may have switched the line and load posts on the circuit breakers.. The breaker is a Blue Seas 60 Amp 285 series resettable breaker. One post is labeled “battery” and one is labeled “aux”. I put one on input and output side of charger. Does it matter which post is on the battery or charger side?
if so, would both “aux” posts run towards charger,
Or would they both orient in the same direction, TV battery to CB1 battery post, CB1 aux post to charger, charger to CB2 battery post, CB2 Aux post to trailer battery?

Thanks,
Erik

Won’t fire it up until I’m sure it’s wired correctly

I don't think it makes a difference. You have hot in on one side and hot out the other. I have the same breakers and never noticed any markings. Mine are working fine.
However an expert will be along shortly

In general, breakers aren’t directional unless the posts are labelled line and load. Some breakers need power on certain components to engage.

John, They are labelled... "Battery" on one post and "Aux" on the other. My thought was the "battery" may be the same as "line". No instructions on package and can't find them on line either.

Maybe "battery" goes to power source and "Aux" goes to electrical component???

Makes sense headed from tow vehicle battery to charger but what about charger to trailer battery?

Copper plated is power in, which should be labelled battery.

Another reason for the dedicated terminals is to avoid any chance of the bimetallic portion of the breaker from possibly protruding through the body of the breaker while energized.

With that in mind, does the breaker on the "Output" side of charger connect with the "Battery" post connected directly to battery also? Kind of like 2 rivers (batteries) flowing to the lake (Charger)?

I'm sure I'm overthinking this, but its what I do best....

The current should be going one way. Tow vehicle battery to charger to trailer battery. I would read batt as source and aux as load. So connect tow vehicle battery as source, batt on cb1, and charger output as source, batt on cb2. Like the original post.

You have them wired the way I would do it. BAT connection on source. The source doesn't have to be a battery. Just think of it as 'where the power is coming from'.

[TedS]

Even the ever truthful internet has confusing answers.

On edit: just asking, is the dc-dc charger directional, polarized? Is cb2 necessary?

But, electrons and also the current (and therefore the power) comes from the negative terminal.

A case of physics and convention not matching.
