Would this help prevent the spark when you connect a battery to a ebike? Please help thank you

No. You need a switch in series that's rated for your application (current/power).

Can you vet a face cover with it

They come with a rubber button cover. not sure if thats what you are asking

Will they work in a '95 Peterbilt 379? Thanks in advance.

As to electrical compatibility, these are spec'd to 50vdc. I guess you are either 12v or 24v so you'd be good to go. Regardless of voltage breakers are current devices, so these will trip at 30amps. Physical mounting position is up to you

Does the push button also function to manually open the circuit? Or only to reset and close the circuit?

it is a reset only. No way to manually open the circuit.
