Question About Fuse Markings

• Low-Breaking Capacity—A minimal ability of the fuse to remain physically intact when overloaded. A low-breaking capacity fuse is readily subject to being physically destroyed if the current surge is great enough.
• High-Breaking Capacity—A high level ability of the fuse to remain physically intact even when the overload is great. The fuse is usually constructed with a ceramic body, rather than glass, and filled with silica sand to absorb a large overload and protect the fuse itself.

Any idea what the fuse voltage would be and where I can purchase them in the USA?
