Circuit breakers

[MrNatural22]

Ok electricians,
Quick question on manual reset-able DC circuit breakers. There are two posts for connection, one is marked AUX and one is marked BAT. does it matter which post you connect each wire to? Are they one way? So basically can battery be connected to AUX post and power out be connected to the BAT post?

It shouldn't matter but there always could be a diode or some other mono-directional device in there. Odds on it just uses the standard thermal strip and electromagnet to sense overload.

For ease of troubleshooting, it'd make sense to connect battery to the battery terminal.

Those breakers usually come with a fact sheet. Does it reference connections?

Here’s the breaker. Pretty standard.

No no fact sheet.
I only ask for appearance purposes. In the component configuration I’ve built it would be mounted wth the lettering upside down. Not a big deal.

Noooooooooooooooooooooooooooooooooo
Not those things

That style unit has been talked about here already, with less than stellar reports.

LOL.... No not another ebay wonder. I got this one thru the local auto parts NAPA store. I hope they don't buy stock from Ebay junk!!!
It does look just like the cheap ones but I've seen some Bussmans that are also quite similar.

I hear ya I've had two defective Ebay paperweights already. If this one takes a sh!t I can return it to the local NAPA (small town courtesy) Then i'm going to fuses.
