HW8 series universal circuit breaker (txij no mus hu ua circuit breaker). Tam sim no ntsuas tau 200-1600A, voltage ua haujlwm AC 400V, 690v. siv rau AC 50Hz, Nws feem ntau yog siv rau kev faib hluav taws xob network. Siv rau kev faib hluav taws xob. Tiv thaiv circuit thiab cov khoom siv fais fab, kom tsis txhob muaj overload, voltage tshuav, luv luv circuit, thiab kev puas tsuaj ntawm ib theem grounded fault. Lub circuit breaker no muaj tsos zoo nkauj, muaj peev xwm tawg tau zoo, tsis muaj flash over. Muaj ntau yam kev tiv thaiv ntse. Siv tau ua kev tiv thaiv xaiv, ua haujlwm raug, zam kev tawm hluav taws xob tsis tsim nyog.

txhim kho kev ntseeg siab ntawm kev muab hluav taws xob. Lub tshuab hluav taws xob no siv tau dav hauv cov chaw tsim hluav taws xob, cov chaw tsim khoom, cov chaw tsuas thiab cov tsev siab niaj hnub.
Tshwj xeeb tshaj yog lub zog faib hluav taws xob hauv lub tsev ntse, Hauv lub zog cua, lub zog hnub ci thiab lwm yam haujlwm ntsuab kuj muaj ntau yam kev siv.
Khoom tuaj yeem txais yuav cov qauv hluav taws xob sab saud lossis cov qauv hluav taws xob qis dua; kos-tawm hom hluav taws xob breaker muaj kev ua haujlwm cais tawm.
Ua raws li tus qauv: GB14082.2, IEC60947-2.
Qhov kub ntawm huab cua ib puag ncig yog-5 ℃ ~ + 40 ℃, qhov kub nruab nrab hauv 24 teev tsawg dua + 35 ℃.
Sau tseg: qhov siab tshaj + 40 ℃ lossis qhov qis tshaj -5′ ℃ ua haujlwm. tus neeg siv yuav tsum tau sib tham nrog lub Hoobkas.

♦Qhov siab ntawm qhov chaw teeb tsa tsis pub tshaj 2000m.
♦Qhov av noo ntawm huab cua hauv huab cua kub yog +40′℃ tsis pub tshaj 50%: Thaum qhov kub qis dua tuaj yeem muaj av noo ntau dua; Piv txwv li, qhov nruab nrab ntawm lub hli ntub tshaj plaws qhov av noo siab tshaj plaws yog 90%, lub caij no, qhov nruab nrab ntawm lub hli qhov kub tsawg tshaj plaws yog 20 ℃ +, Vim yog qhov kub hloov pauv qee zaum ua rau muaj dej noo tshwj xeeb yuav tsum tau ua.
♦Cov theem ua qias tuaj rau theem 3.

Lub Circuit Breaker Lub Circuit Tseem Ceeb ntawm pawg teeb tsa yog V. Thaum lub Circuit tseem ceeb ntawm qhov ntsuas hluav taws xob ua haujlwm tsawg dua lossis sib npaug rau AC400V. Lub Circuit Tswj thiab Lub Circuit Pabcuam ntawm pawg teeb tsa tshwj tsis yog Undervoltage tripping coil thiab lub tshuab tswj ntse ntawm lub zog fais fab transformer thawj kauj zoo ib yam li lub Circuit Breaker. Cov seem yog tag nrho ll: Thaum lub Circuit tseem ceeb ntawm qhov ntsuas hluav taws xob ntau dua AC400V thiab tsawg dua lossis sib npaug rau AC690V. Lub Circuit Tswj thiab Lub Circuit Pabcuam xav tau lub transformer cais los rwb thaiv tsev nrog lub voj voog tseem ceeb. Thiab qhov siab tshaj plaws ua haujlwm rau lub Circuit Tswj thiab Lub Circuit Pabcuam yog AC400V. Pawg teeb tsa ntawm lub Circuit Tswj thiab Lub Circuit Pabcuam yog ll.
