Ubonelelo lweSixhobo soKhuseleko oluMgangatho oMhle oluPhezulu lweThermomagnetic Molded Case Circuit Breaker

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”.
