Question regarding a fuse

[Sekiro]

Hello all, would anyone please help me. I cannot find a fuse that will work with this barrier (device is in the attachment).

I am not very knowledgeable any help would greatly be appreciate.

Why do you want / need a fuse? If this is used in a combustible gas environment, could a blown fuse cause a spark with any inductive wire or load?. Why would you want even to use this module?

By the way, your 2 attachments are the same

It just seems to be a 12V Zener with a series R for input and output and a whole bunch of specs in a fancy box,

The barrier has an internal fuse to limit the power dissipation in case of supply overvoltage. In normal input voltage range, the fuse won't blow, even if barrier output is shorted. So why do you want a fuse?

Thank you for all the replied, the fuse I had blown out and I need to find a replacement. But having a really tough time finding it in any stores.
