Fuses (used with finger-safe fuse disconnect) provides a visible disconnect for troubleshooting.
Fuses will generally coordinate better with each other at higher levels of fault current than will MCCBs with instantaneous trips.
Fuses are less expensive and are more readily available in smaller amperage ranges.
Current-limiting fuses can limit fault current and released energy if high fault current is available.

The fuse application experiencing a blown fuse often leads to troubleshooting first before a new fuse is inserted and circuit energized. This can be viewed as the more productive approach to corrective actions.

You don't state what kind of I/O card it is: relays, transistor, or triacs, although everyone seems to have assumed relays.
If it is a solid-state (triac / transistor), then a circuit breaker will not be fast enough to protect the silicon. Use an ultrafast fuse designed for this sort of application.
