Can I use circuit breaker instead of a fuse to fit into the positive side from the battery?

Q: Hi, I recently purchased this 3000w LF inverter from you, I am just about to fit this into my motorhome, can you advise what size fuse I need to fit into the positive side from the battery? could I use a circuit breaker instead of a fuse???
thank you.

A: Hi, can not use fuse, but can use circuit breaker instead.
