HW8 series universal circuit breaker (Ntawm no hu ua Circuit Court breaker). rated tam sim no 200-1600A, ntsuas ua haujlwm voltage AC 400V, 690v. siv rau AC 50Hz, Nws yog tsuas yog siv rau lub zog faib hluav taws xob. Siv rau kev faib hluav taws xob. Tiv thaiv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, kom muaj kev ywj pheej ntawm overload, tshuav nqi hluav taws xob, luv luv Circuit Court, kev puas tsuaj ntawm ib-theem grounded txhaum. Lub Circuit Court breaker no muaj kev zoo nkauj, muaj peev xwm tawg, xoom nyem dhau. muaj ntau yam kev tiv thaiv kev txawj ntse. Yuav siv tau raws li kev xaiv kev tiv thaiv, kev txiav txim kom raug, zam kom tsis txhob muaj hluav taws xob tsis tsim nyog.

txhim khu kev ntseeg tau ntawm lub hwj chim mov. Qhov no Circuit Court breaker tuaj yeem siv dav hauv cov chaw nres tsheb fais fab. factories. mines thiab niaj hnub high-sawv vaj tse.
Tshwj xeeb tshaj yog cov hluav taws xob faib hluav taws xob hauv lub tsev ntse, Hauv cua fais fab. hnub ci zog thiab lwm qhov project ntsuab kuj muaj ntau yam kev siv.
Cov khoom lag luam tuaj yeem txais cov qauv xaim sab saud lossis cov qauv xaim qis; kos-tawm hom Circuit Court breaker muaj kev rho tawm haujlwm.
Ua raws li tus qauv: GB14082.2, IEC60947-2.
ambient kub yog -5 ℃ ~ + 40 ℃, qhov nruab nrab kub hauv 24h tsawg dua + 35 ℃.
Nco tseg: sab sauv txwv tshaj + 40 ℃ lossis qis qis qis dua -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.
♦ Atmosphere txheeb ze av noo nyob rau hauv lub ambient cua kub yog +40 ℃ tsis tshaj 50%: nyob rau hauv qis kub yuav muaj ntau dua cov txheeb ze av; Piv txwv li, lub hli ntub dej nruab nrab qhov nruab nrab qhov siab tshaj plaws ntawm cov av noo yog 90%, lub caij no, lub hli nruab nrab qhov ntsuas kub tsawg kawg yog 20 ℃ +, Vim tias qhov kub hloov pauv qee zaus yuav tsum tau ua kom muaj kev ntsuas tshwj xeeb.
♦ Cov pa phem rau qib 3.

Lub Circuit Court breaker lub ntsiab Circuit Court ntawm installation qeb yog V. Thaum lub ntsiab Circuit Court ntawm rated ua hauj lwm voltage yog tsawg dua los yog sib npaug rau AC400V. tswj Circuit Court thiab auxiliary Circuit Court ntawm installation qeb tshwj tsis yog lub Undervoltage tripping coil thiab ntse tswj ntawm fais fab mov transformer thawj kauj ib yam li Circuit Court breaker. Tus so yog tag nrho ll: Thaum lub ntsiab Circuit Court ntawm qhov ntsuas hluav taws xob ntau dua AC400V thiab tsawg dua lossis sib npaug rau AC690V. Tswj Circuit Court thiab auxiliary Circuit Court xav tau kev sib cais transformer rau insulate nrog thawj lub voj. Thiab qhov siab tshaj plaws ua haujlwm voltage rau tswj Circuit Court thiab auxiliary Circuit Court yog AC400V. Lub installation qeb ntawm tswj Circuit Court thiab auxiliary Circuit Court yog ll.
