HRC pae taratahi pana ki 160A fuse whakakā momotu
HR17 Ka whakamahia te Momotu Whakawhiti Whakawhiti ki raro i te Ngaohiko Whakatau 690V.Ko te naianei matua ko te 160A ki te 630A. Ko te nuinga o te waa e whakamahia ana hei whakawhiti mana, te whakawhiti wehe me te huringa ohorere i roto i te punaha hiko.
He momo hononga hono: NH00 mo te 160A, NH1 mo te 250A, NH2 mo te 400A me te NH3 mo te 630A
Ngā au kua whakatauhia: 4, 6, 10, 16, 20, 25, 32, 35, 40, 50, 63, 80, 100, 125, 160, 200, 224, 250, 300, 315, 305, 40, 4 me te 630 ngongo,
HR17 momo whakakoi whakakā wehe, whakatauhia ngaohiko whakaraerae AC800V.kua whakatauhia ngaohiko whakahaere 690V.400V, te auau 50HZ.ko nga reiti o naianei 160A ~ 630A te nuinga o te waa e whakamahia ana hei whakawhiti hiko, te wehe i te pana me te huringa ohorere me te mahi o te whakamarumaru i roto i te ara iahiko me te ara iahiko poto teitei me te motuka motuka, kaore i te whakamahia tenei pana ki te whakahaere i te motuka kotahi.
I te wa e whakakapihia ana e te maripi kaaiti, karekau he hikoi hiko o tenei pana ki te taumaha ki nga waahanga-poto te mahi whakamarumaru, ka makona noa i te whakatauranga i kiia e tenei pana ki te whakauru me te meneti ka pakaru te abilitu, ka hanga te raina ki te wehe i nga whakamahinga.
he rite tenei hua ki te paerewa GB14048.3-2002.IEC 947-3(1999)
