Do you need a switch or fuse in addition of circuit breaker?

I have this Blue Sea circuit breaker as main battery fuse and switch: https://www.bluesea.com/products/7149/187-Series_Circuit_Breaker_-_Surface_Mount_200A

Is this enough or should there be a additional switch and/or faster fuse? If so, why?

I think you use a switch only when doing maintainance or when something is wrong, so it's not very frequent. As a fuse circuit breaker could be too slow for some cases with shortcut?

What about high inrush current - can an inverter or MPPT generate that?
