1.Normal Yazvino: Kutanga isu tinofanirwa kuziva yakajairwa saizi yazvino inoyerera kuburikidza nefuse iri mudunhu yakashandiswa.
Kazhinji isu tinofanirwa kuseta kutapudza pamberi, tobva tasarudza zvinoenderana nesimboti inotevera: ndiko kuti, yakajairika nguva ino inofanira kunge iri shoma pane chigadzirwa cheiyo ratidziro yazvino uye yekudzikisa coefficient.
2.Fuse Yazvino: Zvinoenderana neiyo UL maratidziro, iyo fiyuzi inofanira kukurumidza kusanganiswa pane yakarongwa yazvino kaviri. Muzviitiko zvakawanda, zvisinei, kuitira kuti ive fuse yakavimbika, tinokurudzira kuti iyo fuse yazvino ive yakakura kupfuura ka2,5 nguva yakapetwa yazvino.
Uye zvakare, iyo fiyuzi nguva yakakosha, asi zvakare inofanirwa kureva iyo fiyuzi inoratidzirwa dhayagiramu yakapihwa nemugadziri kuita mutongo.
3.Open Circuit Voltage: yakavhurika redunhu voltage inowanzo sarudzwa kuve shoma pane yakatarwa voltage.
Semuenzaniso, kana fiyuzi ine yakatarwa voltage ye dc24v ichishandiswa mudunhu reac100v, zvinokwanisika kubatidza kana kuputsa fiyuzi.
4.Short-redhiyo yazvino: Iyo yakanyanya kukosha yazvino kukosha yatinotenderera kana iyo dunhu ipfupi-kutenderera inonzi pfupi-redunhu razvino. Kune fuses dzakasiyana siyana, iyo yakatarwa bhureki kugona inotsanangurwa, uye isu tinofanirwa kungwarira kuti tisaite pfupi-redunhu razvino kupfuudza ratidziro yedunhu kugona pakusarudza fiyuzi.
Kana fiyuzi ine diki yakaputsika redunhu kugona ikasarudzwa, inogona kutyora fuse kana kukonzera moto.
5.Impact Razvino: Iyo waveform (pulse yazvino waveform) yekucherechedzwa kwesimba kwazvino inoshandiswa kuverenga simba rayo uchishandisa I2T kukosha (Joule inosanganisa kukosha). Iko kukanganisa kwazvino kwakasiyana muhukuru uye kuwanda, uye zvinoitika pane fiyuzi zvakasiyana. Chiyero cheiyo i2t kukosha kweiyo zvazvino kuitika kune fiyuzi i2t kukosha kweimwe pulse inotarisa iyo nhamba yenguva iyo fuse iri inopesana nekukanganisa zvazvino.
