Ma fuse amateteza zida zamagetsi kumagetsi amagetsi ndikuletsa kuwonongeka kwakukulu komwe kumachitika chifukwa chakulephera kwamkati.Choncho, fusesi iliyonse ili ndi chiwerengero, ndipo fuseyi idzawomba pamene mphamvu ikupitirira mlingo.Pamene magetsi agwiritsidwa ntchito pa fusesi yomwe ili pakati pa magetsi osagwiritsidwa ntchito nthawi zonse ndi mphamvu yosweka yomwe yatchulidwa muyeso yoyenera, fuyusiyo idzagwira ntchito moyenera komanso popanda kuwononga chilengedwe.
Kuwonongeka koyembekezeka kwa dera komwe fuseyi imayikidwa kuyenera kukhala kochepa poyerekeza ndi mphamvu yosweka yomwe yafotokozedwa mu muyezo.Apo ayi, pamene cholakwika chikachitika, fuseyi idzapitiriza kuwuluka, kuyaka, kutentha fuse, kusungunuka pamodzi ndi kukhudzana, ndipo chizindikiro cha fuse sichidziwika.Zachidziwikire, kuphwanya mphamvu ya fusesi yotsika sikungakwaniritse zofunikira zomwe zafotokozedwa mulingo, ndipo kugwiritsa ntchito kuvulaza komweko kudzachitika.
Kuphatikiza pa ma fuse resistors, palinso ma fuse ambiri, ma fuse otentha ndi ma fuse odzibwezeretsa okha.Zomwe zimateteza nthawi zambiri zimalumikizidwa motsatizana m'derali, zomwe zimazungulira pakalipano, kupitilira voteji kapena kutenthedwa ndi zinthu zina zachilendo, nthawi yomweyo zimaphatikizana ndikuchita ntchito yoteteza, zitha kupewa kukulitsa vutolo.

The magawo waukulu wa fuseji wamba oveteredwa panopa, oveteredwa voteji, yozungulira kutentha ndi liwiro anachita.Pakali pano, yomwe imadziwikanso kuti breaking capacity, imatanthawuza mtengo wapano womwe fuseyi imatha kusweka pamagetsi ovotera.Mphamvu yogwiritsira ntchito fuseyi iyenera kukhala yotsika ndi 30% kuposa yomwe idavotera pano.Mlingo wapano wa ma fuse apanyumba nthawi zambiri amalembedwa pa kapu yachitsulo, pomwe mphete yamitundu yochokera kunja imayikidwa pa chubu lagalasi.
Mphamvu yamagetsi imatanthawuza mphamvu yoyendetsedwa bwino kwambiri ya fuse, yomwe ndi 32V, 125V, 250V ndi 600V zinayi.Mphamvu yeniyeni yogwiritsira ntchito fuseyi iyenera kukhala yocheperapo kapena yofanana ndi mtengo wamagetsi.Ngati mphamvu yogwiritsira ntchito fuseyi iposa mphamvu yovotera, idzawombedwa mwamsanga.
Mphamvu yaposachedwa ya fuseyi imayesedwa pa 25 ℃.Moyo wautumiki wa ma fusewu ndi wosiyana mosiyanasiyana ndi kutentha kozungulira.Kutentha kozungulira kumapangitsanso kutentha kwa fuseyi, moyo wake umakhala wamfupi.
Liwiro loyankhira limatanthawuza kuthamanga komwe fusesi imayankhira kuzinthu zosiyanasiyana zamagetsi.Kutengera liwiro ndi magwiridwe antchito, ma fuse amatha kugawidwa m'mitundu yoyankhira, mtundu wanthawi yopuma, mtundu wakuchitapo kanthu komanso mtundu waposachedwa.
