Yes but there are two problems.
Most of the simple ones are self reseting and if there is a dead short on the line, they will trip, reset, trip, reset and on and on which is a bad thing and dangerous in the long run.
The DC breakers which look like normal AC circuit breakers with a little switch handle are really expensive and hard to come by. In most cases they are overkill for the job.
A simple DC automotive type fuse is a good solution overall. It is inexpensive and easily replaced. Often they last the lifetime of the device or wiring protected. If you have circuits which are blowing fuses commonly, something else is wrong and should be repaired.
I like the new fuse panel provided with my replacement PD 4645 converter/charger. It has an LED for each fuse position. If the fuse blows, the LED lights up allowing you to easily find which one it is. Very clever.
