Izici zeAma-MCCBs

Ama-MCCBsaklanywe ngemisebenzi eminingana esiza ukuvikela amasistimu kagesi ngendlela ephephile nethembekile.Ezinye izici ezibalulekile ze-MCCB zifaka:

Umthamo omkhulu wokuphuka:Ama-circuit breakers abunjiweziyakwazi ukuphula imisinga efinyelela ezinkulungwaneni zama-ampere, okuwenza alungele ukusetshenziswa kwamandla aphezulu.
Indlela yohambo lwe-Thermal-magnetic: Izinqamuli zesekhethi ezibunjiwe zisebenzisa indlela yohambo lwe-thermal-magnetic ukuze zibone futhi ziphendule kumasekhethi adlulele kanye namafushane.Ama-elementi ohambo olushisayo aphendula ekulayisheni ngokweqile, kuyilapho ama-elementi ohambo kazibuthe aphendula kumasekhethi amafushane.
Isilungiselelo Sohambo Esilungisekayo: Ama-MCCB anezilungiselelo zohambo ezilungisekayo, eziwavumela ukuthi asethelwe ezingeni elifanele lohlelo olufunekayo.
Uhlu olubanzi lwamasayizi ozimele: Ama-MCCB atholakala ngamasayizi ahlukahlukene ozimele, avumela ukuthi asetshenziswe ezinhlotsheni ezihlukahlukene. .I-elementi yohambo olushisayo izwa ukushisa okukhiqizwa ukugeleza kwamandla kumjikelezo futhi igingqa isinqamuli sesekethe lapho i-current idlula isilinganiso sohambo.Isici sohambo lukazibuthe sizwa inkambu kazibuthe ekhiqizwe isekethe emfushane, ikhubekisa isinqamuli sesekethi cishe ngokushesha.Isakhiwo sekhesi elibunjiwe
I-MCCB iqukethe izindlu zepulasitiki ezibunjiwe ezihlala indlela yohambo, abathintwayo kanye nezingxenye ezithwalayo zamanje.
Othintwayo benziwe ngezinto ezisebenza kakhulu njengethusi, kuyilapho indlela yohambo iqukethe umucu we-bimetallic kanye nekhoyili kazibuthe.
