    Isicelo

    I-CJMM1 series molded case circuit breaker (ebizwa ngokuba yi-circuit breaker) iyasebenza kwi-AC 50/60HZ power distribution network circuit ene-insulation voltage elinganisiweyo ye-800V, i-voltage yokusebenza elinganisiweyo ye-690V kunye ne-operation current elinganisiweyo ukusuka kwi-10A ukuya kwi-630A, isetyenziselwa ukusasaza amandla kunye nokuthintela izixhobo zesekethe kunye nombane ukuba zingamonakalisi ngenxa yokugqithiswa kakhulu, i-short circuit, i-under voltage kunye nezinye iimpazamo, ikwasetyenziselwa ukuqala rhoqo kwe-motor kunye nokugqithiswa kakhulu, i-short circuit kunye nokukhuselwa kwe-under voltage. Le circuit breaker inezibonelelo zevolumu encinci, amandla aphezulu okuqhekeka, i-short arcing (okanye i-noarcing) njl. njl., inokuxhotyiswa ngezixhobo ezifana ne-alamu contact, i-shunt release, i-assistant contact njl.njl., yimveliso efanelekileyo kumsebenzisi. I-residual current current breaker inokufakelwa ngokuthe nkqo (ukufakelwa ngokuthe nkqo) okanye ifakwe ngokuthe tye (ukufakelwa ngokuthe tye). Imveliso ihambelana nemigangatho ye-IEC60947-2 kunye ne-Gb140482
