Ixabiso elithengiswayo ngobuninzi CJMM3-125 3P 125Amp Electrical Molded Case Circuit Breaker MCCB Umfanekiso obonisiweyo

Ixabiso elithengiswayo ngexabiso eliphantsi CJMM3-125 3P 125Amp Electrical Molded Case Circuit Breaker MCCB

Inkcazo emfutshane:

I-CJMM3 Moulded case circuit breaker (ebizwa ngokuba yi-circuit breaker) ineempawu zobukhulu obuncinci, amandla aphezulu okuqhekeza, i-arcing emfutshane, kunye ne-anti-vibration. Ifanelekile kwiinethiwekhi zokusasazwa kwamandla ezine-AC 50Hz, i-voltage yokusebenza elinganisiweyo eyi-400V, kunye ne-operating current elinganisiweyo ukuya kwi-250A nangaphantsi. Isetyenziselwa ukusasaza amandla ombane kunye nokukhusela imigca kunye nezixhobo zamandla kwi-overload, i-short circuit kunye nezinye iimpazamo. Ingasetyenziselwa nokutshintsha rhoqo kwi-circuits kunye nokuqalisa rhoqo kwee-motors. I-circuit breaker ingafakwa ngokuthe nkqo (oko kukuthi, ukufakwa ngokuthe nkqo) okanye ngokuthe nkqo (oko kukuthi, ukufakwa ngokuthe nkqo).

Le mveliso ihambelana ne-IEC60947-2 kunye ne-GB/T14048.2 “Izixhobo zokutshintsha kunye nezixhobo zokulawula ezine-voltage ephantsi Icandelo lesi-2: Ii-circuit breakers”.

Iimeko Zokusebenza Nokufakelwa

Ukuphakama kwendawo yokufakela akudluli kwi-2000m.
Ubushushu bomoya obuphakathi;
Umda ophezulu wobushushu bomoya ojikeleze umhlaba awudluli ku +40°C;
Ubushushu bomoya obuqhelekileyo obuhlala kwiiyure ezingama-24 abudluli ku +35°C;
Umda ophantsi wobushushu bomoya ojikeleze umhlaba awukho ngaphantsi kwe -5°C;
Iimeko zomoya:
Umswakama ohambelanayo womoya awudluli kwi-50% xa ubushushu obuphezulu obujikeleze umhlaba buyi-+40°C. Unokuba nomswakama ophezulu xa ubushushu buphantsi. Xa ubushushu obuphakathi obuphakathi benyanga enyangeni enemvula budluli kwi-+25°C, umswakama ohambelanayo womoya awudluli kwi-+25°C. Umswakama ophakathi ohambelanayo yi-90%, kuthathelwa ingqalelo ukufuma kumphezulu wemveliso ngenxa yotshintsho lobushushu.
