Fuse marking

Got a 20 x 5 ceramic 1A Fuse marked F1H. Does the F1H indicate it's a fast blow fuse? It's out of the speed controller of an MHRV system.

F for fast/quick blow, T for timed/slow blow.

Not sure what the H is for.

the H probablly means it's HRC. That is designed with a high breaking capacity.

What is this fuse for? what kind of fuse have you ordered? In general glass fuses are ok inside equipment powered through a domestic socket or similar protection but they have VERY low breaking capacities.

I have a background in electronics so pretty sure most 1A quick blow fuses will be fine but couldn't find an explanation for what the "H" meant on the web.  Fan motor is only around 40W.
