熔斷器（fuse）是指當(dāng)電流超過(guò)規(guī)定值時(shí)，以本身產(chǎn)生的熱量使熔體熔斷，斷開電路的一種電器。熔斷器是根據(jù)電流超過(guò)規(guī)定值一段時(shí)間后，以其自身產(chǎn)生的熱量使熔體熔化，從而使電路斷開；運(yùn)用這種原理制成的一種電流保護(hù)器。熔斷器廣泛應(yīng)用于高低壓配電系統(tǒng)和控制系統(tǒng)以及用電設(shè)備中，作為短路和過(guò)電流的保護(hù)器，是應(yīng)用普遍的保護(hù)器件之一。

保護(hù)功能

短路保護(hù)：在短路電流作用下，熔斷器幾乎立即熔斷（毫秒級(jí)響應(yīng)），切斷故障電路 。 ?

過(guò)載保護(hù)：對(duì)持續(xù)過(guò)載電流（如1.25倍額定電流以上）有延遲熔斷特性，但保護(hù)效果不如專用熱繼電器
