Tlhaloso e qaqileng:

Letoto la ELSF le na le diswitjhi tse matla tsa ho arola tsa mofuta wa fuse tse kopanyang mesebetsi ya sehokelo le setsi sa fuse, ho netefatsa polokeho ya tshebetso le tshireletso ya potoloho. Disebediswa tsena di entswe bakeng sa tshebediso le dihokelo tsa fuse tsa NH00 tse tloaelehileng (mohlala, NT00 RT16-00, max 160A) le NH01 (mohlala, NT1 RT16-1, max 250A), tse tshehetsang mefuta e mengata ya ditekanyetso tsa fuse tse ikgethang ho tloha ho 4A ho isa ho 250A ho latela motlakase o sebetsang (AC: ho fihlela ho 690V; DC: ho fihlela ho 500V).

E hahiloe ka motheo, sekoahelo, le borokho ba ho kopana, switch ena e etselitsoe ho tšoarella le ho sireletseha. Sekoahelo se potoloha ho etsa sebaka se seholo, se bonahalang sa ho itšehla thajana, se fihlela maemo a thata a ho itšehla thajana, 'me se ka tlosoa habonolo bakeng sa ho nkeloa sebaka ke fuse. Li-unit tsena li na le motlakase o lekantsweng oa insulation (Ui) oa 1000V, motlakase o mamellang impulse (Uimp) oa 8kV, le tekanyo e phahameng ea hona joale ea potoloho e khuts'oane ea 50 kA.
