Nhanganyaya:
Molded Case Circuit Breakers (MCCB) chinhu chinodiwa chemagetsi masisitimu, achipa kuchengetedzwa kwekuremerwa uye kuchengetedzwa kwepfupi.Kazhinji, maMCCB anoiswa mubhodhi guru rekugovera simba renzvimbo, zvichiita kuti sisitimu ivharwe nyore kana zvichidikanwa.MCCBs anowanikwa muhukuru hwakasiyana uye ratings, zvichienderana nehukuru hwemagetsi system.
Mugwaro rino, tichabata zvikamu uye zvimiro zveMCCB yakajairwa, mashandiro avanoita, uye kuti ndedzipi mhando dziripo.Tichakurukurawo mabhenefiti ekushandisa rudzi urwu rwekupwanya mune yako magetsi system.
lts rated insulation voltage is 1000V, iyo inokodzera kusawanzo shandura uye mota inotanga mumaseketi ane AC 50 Hz, yakayerwa kushanda voltage kusvika ku690V uye yakayerwa ikozvino kusvika 800ACSDM1-800 isina kuchengetedzwa kwemota).

Zvinhu zvakakosha zvikuru
● Mutambo wedunhu une overload, pfupi pfupi uye undervoltage kudzivirira mabasa, izvo zvinogona kudzivirira mutsara uye midziyo yemagetsi kubva pakukuvara.Panguva imwecheteyo, inogona kupa dziviriro isina kunangana nevanhu, uye inogona kupawo dziviriro yenguva refu yekumisa kukanganisa kusingaonekwe nepamusoro-ikozvino kuchengetedzwa, izvo zvinogona kukonzera njodzi yemoto.
● Muchengeti wedunhu ane maitiro ehuwandu hudiki, kukwirira kwepamusoro kuputsa, kupfupika kupfupika uye anti vibration
● Mutambo wedunhu unogona kuiswa vertically uye horizontally
● Mutambo wedunhu haugoni kuchinjwa, kureva kuti, 1, 3 uye 5 chete inobvumirwa semagetsi emagetsi, uye 2, 4 uye 6 zviteshi zvekutakura.
● Mutambo wedunhu unogona kugoverwa kuva wiring mberi, wiring kumashure uye plug-in wiring

Chii chinonzi MCCB?
MCCB ipfupi fomu reMolded Case Circuit Breaker.Ndiyo muenzaniso wakajairika wemagetsi ekuchengetedza chigadziro chinowanzopfuura kusashandiswa kana mutoro wezvino wakakwira zvakanyanya kupfuura muganhu weiyo miniature circuit breaker.
Iyo MCCB inopa dziviriro pazvikanganiso zvedunhu pfupi uye inotoshandiswa kushandura maseketi.Inogona kushandiswa kune yakakwirira ikozvino ratings pamwe nekukanganisa nhanho, kana iri nyaya yezvishoma zvinangwa zvemba.Iwo akakura azvino zviyero uye yakakwirira yekutyora simba muMolded Case Circuit Breaker zvinoreva kuti ivo vakatokodzera zvikonzero zveindasitiri.
MCCB inoshanda sei?
Iyo MCCB inoshandisa tembiricha inonzwira tembiricha (iyo inopisa chinhu) ine yazvino inonzwa yemagetsi emagetsi mudziyo (iyo magineti chinhu) kuti ipe nzira yekufamba yekudzivirira uye yekuzviparadzanisa nevamwe.Izvi zvinoita kuti MCCB ipe:
Overload Protection,
Electrical Fault Dziviriro kubva kupfupi wedunhu mafungu, uye
Electrical Switch yekudzima.
Ndeupi musiyano uripo pakati peMCB neMCCB?
MCB uye MCCB anowanzo kushandiswa redunhu kudzivirira michina.Midziyo iyi inopa dziviriro kubva pamusoro peazvino uye mapfupi maseketi.Pane misiyano mishoma pakati pezvishandiso zviviri izvi kunze kwekuyerwa kwazvino.Parizvino chiyero cheMCB chinowanzoitika pasi pe125A, uye MCCB inowanikwa kusvika pachiyero che2500A.
