I-Circuit breaker PowerPacT H 30A 3 pole 600VAC 25kA lugs thermal magnetic 80% power supply circuit breaker schneider electric tr

Ama-circuit breaker e-PowerPacT H-Frame aklanyelwe ukuvikela amasistimu kagesi emonakalweni obangelwa ukugcwala kakhulu namasekhethi amafushane. Ziza nokukhetha kwamayunithi wokuvikela uhambo lwe-thermal-magnetic noma i-Micrologic electronic, enikeza ukuvikeleka okuqinile okufana nalokho okusetshenziswa ukudluliselwa kwesimo esiqinile kwezinye izinhlelo zokusebenza. Ukuqonda ukuthi iyini i-circuit breaker (i-apa itu circuit breaker), kubalulekile ukuqaphela ukuthi lawa maphuli ahlanganisa ukuvikeleka kokudluliswa kwe-relay ukuze kuthuthukiswe ukuphepha.

Ngaphezu komsebenzi wawo oyinhloko, ama-PowerPacT H-Frame breaker ayatholakala njengama-Miniature Circuit Breakers (MCB) kanye ne-Earth Leakage Circuit Breakers (ELCB), ahlinzeka ngezixazululo ezihlukahlukene. Lokhu kufaka phakathi i-SPD (Surge Protection Device) isinqamuli sesekethe, esiklanyelwe ngokukhethekile ukusingatha ukukhuphuka kwamandla kagesi. Ukuze kube lula, amanye amamodeli eza ne-relay enesixhumanisi, ukwenza lula ukufakwa nokugcinwa.

Wonke amamodeli afaka othintana nabo abazungezisayo bekhefu elikabili, okunciphisa ngempumelelo amandla aphezulu ngesikhathi samaphutha esekethe emfushane. Ukwengeza, i-PowerPacT ngayinye i-circuit breaker ihlanganisa inkinobho ehlanganisiwe yokusunduza ukuya ohambweni kukhava yokuhamba mathupha.

Kutholakala ekumisweni kokukhweza kweyunithi ye-2-pole kanye ne-3-pole, kanye nokwakhiwa kwe-I-Line, ama-PowerPacT H-Frame breaker eza nama-lugs kuwo womabili layini kanye nezinhlangothi zokulayisha. Ngokuphawulekayo, i-SSR yesigaba sesithathu sokudlulisa isimo esiqinile kanye nokudluliselwa kwe-AC yesimo esiqinile kungabuye kuhlanganiswe nalawa masistimu ukuze kube nokulawula okuthuthukile nokuvikelwa. I-PowerPacT H, 30A, i-3-pole circuit breaker inamandla okuphuka angu-25kA ku-600VAC kanye nesilinganiso samanje esiqhubekayo esingu-80%, kuyilapho ihlanganisa ukuqapha kwamanje okusele ukuze kuthuthukiswe ukuphepha.

Ukuze uthole ukuqapha okuphelele kwesistimu, idivayisi yokuqapha i-voltage ingabhangqwa nalawa maphuli. Kuzinhlelo zokusebenza zesikhathi, ukushintsha kwesibali sikhathi se-DC kungasetshenziswa. Ngokunamathela kumazinga e-UL, CSA, NOM, kanye ne-IEC futhi ephethe uphawu lwe-CE, lezi zephuli mthetho ziqinisekisa ukuhambisana nokuthembeka, okuzenza zilungele izinhlelo zokusebenza ezahlukahlukene zezimboni nezentengiso.
