Chotsukira Chotsalira cha ALFR Current Current (RCCB)
Chogulitsa Tsatanetsatane
Kufotokozera kwa Zamalonda
Mndandanda wa ALFR RCCB umapereka zotsekera ma circuit breakers za Type A, AC, ndi S, zopangidwa kuti zigwiritsidwe ntchito m'nyumba, m'mabizinesi, komanso m'mafakitale, mogwirizana ndi miyezo ya EN/IEC 61008-1. Ndi mphamvu ya conditional short-circuit yovomerezeka mpaka 10kA komanso ma currents angapo ovotera kuyambira 16A mpaka 100A, chinthuchi chili ndi njira yotulutsira ma electromagnetic release. Mtundu wa Type S umaphatikizapo kuchedwa kochepa kwa nthawi yosagwira ntchito kwa 40ms kuti upewe kugwedezeka kosafunikira, zomwe zimapangitsa kuti ikhale yoyenera ngati switch yayikulu kapena yogwiritsidwa ntchito ndi zoteteza za Class II surge.
Chopangidwa ndi kapangidwe kamakono, chimathandizira kulumikizana ndi ma conductors mpaka 35mm² komanso kukhazikika kolimba kudzera mu DIN rails. Chizindikiro cholumikizira chamitundu iwiri (chofiira ngati chatsekedwa, chobiriwira ngati chatsegulidwa) chimathandizira chitetezo chogwira ntchito, pomwe mitundu yonse imapereka kukana kwa mafunde amagetsi mpaka 5kA. Ndi mawaya osavuta kugwiritsa ntchito omwe amagwirizana ndi mabasi ndi ma terminals amtundu wa pin, komanso mulingo woteteza wa IP20, chimatsimikizira magwiridwe antchito odalirika m'malo osiyanasiyana.
Magawo a magwiridwe antchito akuphatikizapo mayeso olimba a kupirira (nthawi yogwirira ntchito yotsegula/kuchotsa katundu) ndi zofunikira zenizeni za nthawi yosweka (zosinthidwa kutengera mtundu wa kutayikira ndi mtengo wamagetsi). Chosweka cha Mtundu S chimapereka chitetezo chosankha, chochepetsa kwambiri kusokonezeka kwa magetsi kosafunikira pamene chikukwaniritsa nthawi yodzipatula yokha ya 0.2s kapena 0.4s, kupereka kudalirika kofunikira pazochitika zoteteza magetsi zotsalira zomwe zimafunidwa kwambiri.

Mawonekedwe
Popanga zipangizo zotsalira zamagetsi, ukadaulo wopanga ndi mtundu wa mayeso obwerezabwereza, miyezo ya IEC/EN 61008 inaganiziridwa. Zinthu zofunika ndi izi:
✓ Kapangidwe katsopano
✓ Kulumikizana kwa ma conductor ndi mabasi ndi kosavuta kugwiritsa ntchito
✓ Kukana kukwera kwa mphamvu zamagetsi; kugwedezeka kosafunikira sikuchotsedwa
✓ Kukhazikitsa njanji yolumikizira ya 35 mm mosavuta komanso motsatira EN 60715
✓ Kuwonetsa mitundu yowonjezera ya malo akuluakulu olumikizirana (ofiira: olumikizirana atsekedwa, obiriwira: olumikizirana atsegulidwa)
✓ Mtundu S: Mtundu wosankha, RCD yokhala ndi nthawi yosagwira ntchito ya osachepera 40 ms
✓ Kukana kwambiri mphamvu yamagetsi mpaka 5 kA (miyezo ya IEC imafuna 3 kA).
✓ Imakwaniritsa zofunikira pa nthawi yopunthwa masekondi 0.4 kapena 0.2 (kudula kokha).
✓ Mtundu S umagwiritsidwa ntchito ngati chotsegula main circuit kapena pamodzi ndi zoteteza mphamvu zamagetsi za kalasi II (C).
✓ Amachepetsa kwambiri kugwedezeka kosafunikira.
