Solar Charging Circuit Breaker(s) - Amp Rating?

[Great Eggstrications]

I'm installing circuit breakers on both sides of my solar controller, and fear, doubt, and uncertainty - as they often do - entered the equation. I'm waiting for some next-day 8 AWG terminal connectors with small screw holes (#10) for the terminals on my Samlex controller so I can make up 4 proper jumpers to go between the breakers and the controller, and since I had time to sit back and think about things, it occurred to me that I didn't know for sure whether the breakers actually have a source end and a load end. I was assuming that it didn't matter, but... what do I know?

There are some forum members out there that are familiar with such matters, and I appeal to them to offer their expertise. There is nothing definitive in the product info on Amazon. While the (+) and (-) sides are clearly marked, there is nothing to indicate source and load ends.

There is a schematic (cryptically to me) showing semi-circles, pieces of a square wave, and what appear to be a couple of diodes but are really asterisks. No idea what that's trying to tell me. Poking around on the interwebs, I see talk about arc-suppression issues in DC breakers, but nothing definitive about source vs. load for these breakers and this application.

Argggg- can somebody please help!? Thanks...

FWIW (and that may be nothing) ....

• I have several BlueSea (Carling Technologies) flush-panel-mount 'toggle breakers' with the "Load" and "Line" screw-terminals labeled
• I have many snap-in-breaker-box 'toggle breakers' in various applications (with a screw terminal only on the "Load" side, the "Line" side being a buss-tab receiver slot)

In all cases, when the toggle-handle is flipped to the "Line" side, the breaker is "ON"; when the toggle-handle is flipped to the "Load" side, the breaker is "OFF / tripped / open".

If "ON" and "OFF" are not labeled and you don't have a meter handy, on all of mine there's noticeably more force required to flip the toggle "ON" compared to "OFF".

Make of that what you will, good luck!

The arcs (less than semi-circles) are the circuit breaker part; the schematic also includes separate switch symbols for the manual switching (linked together). But I don't know from the schematic what end is supposed to be the load, or if there is any significance to the square section.
