I-CJMM1E 1000V 250A 3P yomgangatho ophezulu ye-elektroniki ye-MCCB Moulded case circuit breaker

Inkcazo emfutshane:

·I-CJM1E series electronic plastic case circuit breaker (ebizwa ngokuba yi-circuit breaker), efanelekileyo kwi-AC 50H2 okanye i-60Hz), i-insulation voltage yayo elinganisiweyo yi-1000V, i-voltage yokusebenza elinganisiweyo yi-690V nangaphantsi, kwaye i-operating current elinganisiweyo ifikelela kwi-800A yokutshintsha rhoqo kwiisekethe. Kwaye i-motor isetyenziselwa ukuqala rhoqo. I-circuit breaker ine-overload long delay inverse time limit, i-short circuit short delay time limit, i-short circuit short delay time limit fixed, i-short circuit instantaneous and undervoltage protection, i-residual current protection (optional), kunye ne-phase loss protection function (optional). Ingakhusela imigca kunye nezixhobo zamandla ekonakaleni. I-circuit breaker ineempawu zokhuseleko ezipheleleyo nezichanekileyo, ezinokuphucula ukuthembeka kokunikezelwa kombane kwaye ziphephe ukucima kombane okungeyomfuneko.

·Ii-circuit breakers zahlulwe zibe ziintlobo ezimbini: Uhlobo lwe-M (uhlobo oluphezulu lokuqhekeza) kunye nohlobo lwe-H (uhlobo oluphezulu lokuqhekeza) ngokwemilinganiselo yazo yokunciphisa ukuqhekeza ii-short circuit. Esi sixhobo sokuqhekeza ii-circuit sineempawu zobukhulu obuncinci, amandla aphezulu okuqhekeza, i-arcing emfutshane, kunye ne-anti-vibration.

·I-circuit breaker ingafakwa ngokuthe nkqo (oko kukuthi, ngokuthe nkqo) okanye ngokuthe nkqo (oko kukuthi, ngokuthe nkqo).
·I-circuit breaker ayinakuguqulwa, oko kukuthi, yi-1, 3, kunye ne-5 kuphela ezivumelekileyo ukudityaniswa kwiintambo zombane kwaye ezi-2, 4, kunye nezi-6 zivumelekile ukudityaniswa kwiintambo zomthwalo.
