快(kuai)斷保(bao)險絲(si)管一般(ban)是(shi)用(yong)在阻(zu)性(xing)負載的(de)(de)電路上(shang)(shang)，比(bi)如(ru)電熱(re)水壺(hu)、電爐、取暖器上(shang)(shang)面有電熱(re)絲(si)的(de)(de)電器，因為電熱(re)絲(si)都是(shi)屬于阻(zu)性(xing)負載，阻(zu)性(xing)負載的(de)(de)工作電流基(ji)本上(shang)(shang)是(shi)沒(mei)有太大變化的(de)(de)，所(suo)以需要(yao)用(yong)快(kuai)斷（速熔(rong)）保(bao)險絲(si)。或(huo)者(zhe)需要(yao)保(bao)護IC等敏感貴(gui)重器件的(de)電路(lu)中(zhong)也需要采用快斷保險絲。當負載發生短(duan)路(lu)的(de)時候以便及時熔斷進行保護。 

而慢斷(duan)保(bao)險(xian)(xian)(xian)(xian)(xian)絲(si)即延遲保(bao)險(xian)(xian)(xian)(xian)(xian)絲(si)，主要是(shi)用于(yu)感(gan)性(xing)(xing)負載(zai)(zai)，或者(zhe)是(shi)容(rong)(rong)性(xing)(xing)負載(zai)(zai)，例如：方形保(bao)險(xian)(xian)(xian)(xian)(xian)絲(si)、圓(yuan)形保(bao)險(xian)(xian)(xian)(xian)(xian)絲(si)、塑料封裝等(deng)微(wei)型保(bao)險(xian)(xian)(xian)(xian)(xian)絲(si)一(yi)(yi)(yi)般(ban)在(zai)(zai)開(kai)關電(dian)(dian)(dian)源里面是(shi)非(fei)常(chang)常(chang)見的(de)。在(zai)(zai)開(kai)關電(dian)(dian)(dian)源中，有一(yi)(yi)(yi)個容(rong)(rong)量(liang)非(fei)常(chang)大的(de)電(dian)(dian)(dian)解電(dian)(dian)(dian)容(rong)(rong)，電(dian)(dian)(dian)容(rong)(rong)在(zai)(zai)剛通上電(dian)(dian)(dian)的(de)時(shi)候接近于(yu)短(duan)路，其充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)(liu)非(fei)常(chang)大，這(zhe)時(shi)候整機的(de)電(dian)(dian)(dian)流(liu)(liu)(liu)可(ke)能(neng)就(jiu)會超(chao)過了(le)它(ta)的(de)額定工(gong)作(zuo)的(de)電(dian)(dian)(dian)流(liu)(liu)(liu)，如果用快斷(duan)保(bao)險(xian)(xian)(xian)(xian)(xian)絲(si)很可(ke)能(neng)在(zai)(zai)電(dian)(dian)(dian)路上通電(dian)(dian)(dian)的(de)一(yi)(yi)(yi)瞬(shun)(shun)(shun)間因(yin)電(dian)(dian)(dian)容(rong)(rong)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)(liu)過大就(jiu)導致保(bao)險(xian)(xian)(xian)(xian)(xian)絲(si)損(sun)壞(huai)，注(zhu)意(yi)此時(shi)不(bu)(bu)要更換大點電(dian)(dian)(dian)流(liu)(liu)(liu)的(de)保(bao)險(xian)(xian)(xian)(xian)(xian)絲(si)，可(ke)能(neng)是(shi)其他原因(yin)如電(dian)(dian)(dian)路出現問題電(dian)(dian)(dian)路板壞(huai)了(le)，但是(shi)保(bao)險(xian)(xian)(xian)(xian)(xian)絲(si)還(huan)是(shi)好的(de)。在(zai)(zai)電(dian)(dian)(dian)容(rong)(rong)通電(dian)(dian)(dian)一(yi)(yi)(yi)瞬(shun)(shun)(shun)間產(chan)生的(de)大電(dian)(dian)(dian)流(liu)(liu)(liu)不(bu)(bu)會使保(bao)險(xian)(xian)(xian)(xian)(xian)絲(si)損(sun)壞(huai)，不(bu)(bu)影響電(dian)(dian)(dian)路正常(chang)工(gong)作(zuo)，感(gan)性(xing)(xing)負載(zai)(zai)比如電(dian)(dian)(dian)機壓縮機，這(zhe)些負載(zai)(zai)在(zai)(zai)啟動的(de)一(yi)(yi)(yi)瞬(shun)(shun)(shun)間，電(dian)(dian)(dian)流(liu)(liu)(liu)非(fei)常(chang)大，所以像感(gan)性(xing)(xing)負載(zai)(zai)或者(zhe)容(rong)(rong)性(xing)(xing)負載(zai)(zai)工(gong)作(zuo)電(dian)(dian)(dian)流(liu)(liu)(liu)不(bu)(bu)穩定的(de)，就(jiu)需要用到慢斷(duan)保(bao)險(xian)(xian)(xian)(xian)(xian)絲(si)，使其抬高(gao)抗脈沖能(neng)力(li)。

另外并不是所有(you)的(de)(de)保(bao)險絲(si)都有(you)快斷(duan)(duan)(duan)和慢(man)斷(duan)(duan)(duan)之分，一般只(zhi)有(you)一次性(xing)保(bao)險絲(si)和玻璃陶瓷管(guan)狀保(bao)險絲(si)，因為它們需(xu)要考慮到是否承受(shou)瞬間(jian)脈沖電流(liu)。因為快熔斷(duan)(duan)(duan)和慢(man)熔斷(duan)(duan)(duan)保(bao)險絲(si)主要區別在(zai)于(yu)對(dui)瞬間(jian)脈沖的(de)(de)承受(shou)能(neng)力，也(ye)就說慢(man)斷(duan)(duan)(duan)保(bao)險絲(si)其延時(shi)特性(xing)表現在(zai)電路出現非故障脈沖電流(liu)時(shi)保(bao)持(chi)完(wan)好(hao)，且能(neng)對(dui)長時(shi)間(jian)的(de)(de)過載提供保(bao)護，以此來保(bao)障設備的(de)(de)正(zheng)常運行。 

霖達電(dian)子保險絲(si)的優(you)點有很(hen)多(duo)：限流特性好(hao)、分斷能(neng)力(li)高(gao)(gao)、尺寸多(duo)樣齊全、性價比高(gao)(gao)、選擇性好(hao)等。最后，也建議(yi)大家在選型的時(shi)候(hou)多(duo)多(duo)考慮保險絲(si)所使(shi)用(yong)的環境和(he)(he)產品設備，以(yi)確保使(shi)用(yong)的安全性和(he)(he)可靠性。
