UL 248-1:2000 pdf download.Low-Voltage Fuses - Part 1:General Requirements.
2.1.3.2 Filler
Material used to fill a section or sections of a fuse.
2.1.4 Contacts
The external metaNic parts of the fuse used to complete the rcuft. Also referred to as ferrules, caps, blades, or terminals.
2.1.5 Element
The fusible portion of the fuse which acts, during an overcurrent condition, to clear the circuit: also referred to as a link.
2.1.5.1 Renewal element
The part ot a renewable fuse that is rep4aced after interruption to restore the fuse to operating condition,
2.2 General terms
2.2.2 Current-limiting fuse
A fuse that, within a specified overcurrent range, limits the cleanng time at rated voltage to an interval equal to or less than the first major or symmetrical current loop duration: and limits the peak current to a value less than the available peak current.
2.2.5.1 Ambient temperature
The temperature 01 the air surrounding the fuse,
2.2.7,1 Low melting point fuse
A fuse that will open in an ambient temperature of 200°C when carrying 10 percent of rated current.
2.2.7.2 Microfuse
A supplemental fuse, the body of which has no principal dimension exceeding 10 mm (0.4 in), excluding the leads or terminals.
