Makhalidwe aMCCBs

MCCBsamapangidwa ndi ntchito zingapo zomwe zimathandiza kuteteza machitidwe a magetsi m'njira yotetezeka komanso yodalirika.Zina mwazinthu zazikulu za MCCB ndi izi:

Kuthamanga kwakukulu:Zopangira ma circuit breakersamatha kuthyola mafunde mpaka masauzande a ma amperes, kuwapanga kukhala abwino kwa mapulogalamu amphamvu kwambiri.
Makina oyendera maginito otenthetsera: Magawo omangika omangika amagwiritsa ntchito njira yoyendera maginito kuti azindikire ndikuyankha mabwalo opitilira muyeso komanso afupi.Maulendo otenthetsera amayankha mochulukira, pomwe maginito aulendo amayankha mabwalo aafupi.
Mayendedwe Osinthika: Ma MCCB ali ndi makonda osinthika, omwe amawalola kukhazikitsidwa pamlingo woyenera wa pulogalamu yomwe mukufuna.
Zosiyanasiyana makulidwe a chimango: MCCBs zilipo mu makulidwe osiyanasiyana chimango, amene amalola kuti ntchito zosiyanasiyana applications.Ntchito mfundo ya kuumbidwa mlandu circuit breaker Mfundo ntchito ya MCCB zachokera matenthedwe-maginito tripping limagwirira .Gawo laulendo wotenthetsera limazindikira kutentha kobwera chifukwa chakuyenda kwapano muderali ndipo limayendetsa chophwanyira dera pomwe madziwo apitilira paulendo.Mphamvu ya maginito yaulendo imazindikira mphamvu ya maginito yopangidwa ndi kagawo kakang'ono kozungulira, kugwetsa chophwanyira pafupifupi nthawi yomweyo.
MCCB ili ndi nyumba yapulasitiki yopangidwa ndi pulasitiki yomwe imakhala ndi makina oyendera maulendo, zolumikizirana komanso zonyamulira zamakono.
Zolumikizanazo zimapangidwa ndi zinthu zochititsa chidwi kwambiri monga mkuwa, pomwe njira yaulendo imakhala ndi mzere wa bimetallic ndi koyilo yamaginito.
