The HINODE 660GH-125ULTC FUSE is a fast-acting fuse that shuts down equipment in a matter of microseconds, even in cases of short-circuit accidents that ordinary fuses (slow-blow fuses) and circuit breakers cannot prevent. Compact and lightweight, it's also great for quick cut-off action when blocking off. Longevity in the face of fluctuating electric current. There is a large selection of current ratings available. Fuses should not be used at more than 50% of their rated current. Arc re-ignition is possible if the fusing current is less than 8 times the fuserated current. The fuse should be used in conjunction with other protectors in this case.
