施加过负荷电压时，在规定的时间内熔断，对电路起保护作用。
Can be fusible during the stated time for protecting the circuit once wording at the required overload voltage.
此可熔断元件恰当的形状和横截面使其可连续通过额定电流，而对于严重过负荷或短路，按规定的时间一电流特性而熔断。
This element is of proper shape and cross-section to carry rated current continuously and to melt in accordance with a specific time-current characteristic on heavy overload or short circuit.
熔断器时间-电流特性如图3，最小开断电流以上部分为虚线。
See chart 3 for the fuse time-current property. The upper section above the minimum break current is broken line.
