An arc fault circuit interrupter (AFCI) ndi chipangizo chomwe chimachepetsa zotsatira za arcing zolakwika mwa kuchotsera mphamvu dera pamene vuto la arc lidziwika.Zolakwa za arcing izi, ngati ziloledwa kupitilira, zitha kukhala pachiwopsezo choyatsa moto nthawi zina.
Ukadaulo wathu wotsimikizirika pa sayansi yachitetezo ndi uinjiniya umatithandiza kuti tizitha kugwiritsa ntchito zida zonse zodzitchinjiriza, kuphatikiza cholandirira GFCI, ma portable ndi ma circuit breakers.Njira imodzi yotsimikizira imakupatsani mwayi wopindula kuchokera ku liwiro lachangu kupita kumsika.Njira yowongoka komanso yofulumira iyi imapulumutsa nthawi ndi ndalama kudzera mu pulogalamu yotsimikiziridwa bwino yapadziko lonse lapansi.Ntchito yathu yayikulu, yosinthika yantchito imakhudza kafukufuku ndi chitukuko, Global Market Access, kukhazikitsa ndi kugwiritsa ntchito kumapeto.
Zofunikira za AFCI za Global Market Access
Ma AFCI amawunikidwa motsatira mfundo zotsatirazi kuti azitsatira ndi chitetezo:

Circuit Breaker AFCI (Izi zimafufuzidwanso ku UL 489 Edition 13, Standard for Molded-Case Circuit Breakers, Molded-Case Switches, ndi Circuit-Breaker Enclosures.)
Ma AFCI amapangidwa kuti azigwiritsidwa ntchito m'nyumba.Kuchuluka kwa mitundu yosagwirizana ndi 20 A 120 V AC, 60 HZ mabwalo kapena 120/240 Vac kapena 208Y/120 V machitidwe a magawo atatu.Cord AFCIs adavotera mpaka 30 A.
Zofunikira zatsopano zogwirizanitsa kusiyana pakati pa TIL M-02A ndi CSA-C22.2 No. 270-16 zikugwira ntchito kuyambira pa Meyi 23, 2019. Timapereka ntchito zofufuzira zoyambira, komanso ntchito zowunikira komanso zotsimikizira, kuti zikuthandizeni kuwunika. ndi kuyesa pokonzekera kutulutsidwa kwa zofunikira zosinthidwazi.
