Apparently mr sharkey indicates greater arcing potential in DC (though AC is even better at arcing?!?)

But you are at 48 volts, and this breaker regularly sees 170 volts. And you wanted cheap

BigMouse adds:

Hmm, I remember from A&P school that DC switches have to have a higher rating than an AC switch because of the arc caused by turning it on or off. AC is able to sustain an arc, but a DC arc does more damage. This is why TIG welders have an high frequency AC 'starter' circuit, then once an arc is established, it switches over to the high-current DC.

I'm looking forward to seeing how you made your terminal ends. I'm getting to the point where I will need some, and I'm planning on using your method.
