When selecting and replacing overcurrent protective devices in electrical and electronic equipment, technicians must verify both operating specifications stamped on the component body. What two fundamental ratings define the safe operational limits of a standard cartridge fuse?
Cevap:Every standard cartridge fuse has two critical ratings: the 【current】 rating, which defines the maximum continuous electrical flow the element can carry before melting, and the 【voltage】 rating, which indicates the maximum circuit potential the fuse can safely interrupt without allowing an electrical arc to sustain across the blown element.
Cevap
The first blank is current (or amperage/ampere), and the second blank is voltage (or working voltage/volt).
A fuse is an overcurrent protective device whose primary function is dictated by its current rating (in amperes), which determines the current magnitude required to melt the fusible element. Its secondary rating is its voltage rating (in volts), which specifies the maximum operating circuit voltage under which the fuse can safely extinguish and prevent an electrical arc once blown.
