ALF6K Miniature Circuit Breaker (DC)

Chotsekera ma circuit cha DC ALF6K Series miniature ndi choyenera kuteteza ma overload ndi short-circuit mu ma circuit a 50/60Hz, okhala ndi voltage yovomerezeka ya 250V/500V DC ya single-pole ndi 500V DC ya ma three-pole kapena four-pole configurations, komanso current yovomerezeka kuyambira 0.5A mpaka 63A. Amagwira ntchito mkati mwa kutentha kwa -5°C mpaka +40°C ndipo ali ndi mphamvu yosweka ya 6kA kapena 10kA. Zipangizozi zimapereka chitetezo chofunikira kwambiri cha ma circuit pamagetsi okhala m'nyumba, amalonda, komanso a mafakitale opepuka.

Kufotokozera kwa Zamalonda

Chotsekera ma circuit cha DC ALF6K miniature chimapereka chitetezo cha overload ndi short-circuit kwa ma DC system, chomwe chili ndi 250V/500V DC (1-pole: 250V, 3/4-pole: 500V) chokhala ndi 0.5A-63A current range. Chokhala ndi ukadaulo wowonjezera wa arc-extinguisher, chimakwaniritsa mphamvu ya 2500A breaking (DC) ndipo chikutsatira IEC 60947-2.

Kugunda kwa maginito otenthetsera kumatsimikizira kugwira ntchito molondola kuyambira -5°C mpaka +40°C, mothandizidwa ndi ntchito zamagetsi 4,000 ndi maginito 10,000. Ndi m'lifupi mwake wa 18mm, kulumikizana ndi polarity, ndi zizindikiro zoyendera, imathandizira mawaya amkuwa a 1.5-16mm² (torque ya 1.2-3.0Nm).

Zabwino kwambiri pamakina a PV, malo ochapira magetsi a EV, ndi mapanelo ogawa magetsi a DC, zomwe zimapereka chitetezo chofunikira kwambiri pamagetsi obwezerezedwanso komanso ma DC circuits a mafakitale.
