250V DC Miniature Circuit Breaker

Tiv thaiv koj cov DC circuits nrog CDADA DAB7-63 250V DC Miniature Circuit Breaker (MCB) - ntsuas txog 250V DC, tsim los ntawm Shanghai DADA Electric CO., LTD, lub Hoobkas txhim khu kev qha hauv Suav teb, kom ntseeg tau ntau dhau thiab kev tiv thaiv luv luv hauv niaj hnub hnub ci photovoltaic (PV), kev sib txuas lus thiab kev lag luam, DC roj teeb.

Tsis zoo li tus qauv AC breakers, DAB7-63 tshwj xeeb yog tsim los rau DC daim ntaub ntawv, qhov twg arc extinction yog nyuaj vim qhov tsis tu ncua voltage polarity. Nrog lub peev xwm tawg siab ntawm 6,000A ntawm DC 250V, nws cuam tshuam qhov cuam tshuam tam sim no los tiv thaiv kev puas tsuaj los ntawm kev rov qab tam sim no, kev tawm tswv yim inverter, lossis txoj hlua tsis ua haujlwm - ua rau nws yog ib qho tseem ceeb ntawm kev nyab xeeb hauv vaj tse thiab kev lag luam hnub ci kev teeb tsa.

Muaj nyob rau hauv 13 qhov ntsuas tam sim no (1A-63A) thiab 1P teeb tsa rau 250V DC, nws kuj ntsuas rau 2P (500V), 3P (750V), thiab 4P (1000V) rau siab dua-voltage PV arrays. Lub breaker nta ob txoj kev xaiv (cable los yog busbar), qhia meej txog txoj hauj lwm qhia, thiab ceev-ua / ceev-tawg mechanism rau txhim kho arc suppression. Ua raws li IEC 60947-2, IEC 60947-8, CCC, thiab EU RoHS, nws ua kom muaj kev nyab xeeb thoob ntiaj teb thiab ib puag ncig cov qauv.

★ Hnub Ci PV Npaj

Qhov tseem ceeb rau kev tiv thaiv PV modules los ntawm kev rov qab tam sim no thiab inverter tsis ua hauj lwm tawm tswv yim - txhim kho kev ntseeg tau.

★ Muaj peev xwm tawg

6kA ntawm 250V DC ua tau raws li qhov yuav tsum tau ua rau feem ntau cov tsev nyob thiab kev lag luam me hnub ci kev teeb tsa.

★ Daim ntawv pov thawj thoob ntiaj teb

IEC + CCC + RoHS = kev ntseeg siab hauv Asia, Europe, Africa, thiab Latin America.

★ Tus neeg siv-Safe Design

Clear contact position window tiv thaiv kev ua haujlwm tsis raug; dual thaiv kev yooj yim rau kev sib koom ua ke ntawm vaj huam sib luag.

★ Kev ua haujlwm dav dav

Kev ua haujlwm tau ntseeg tau los ntawm -35 ° C (cov huab cua txias) txog + 70 ° C (kub rooftops lossis enclosures).

FAQ

Q1: Kuv puas tuaj yeem siv AC MCB rau DC 250V circuits?

A1: Tsis yog. AC breakers cia siab rau xoom-hla los tua arcs-DC tsis muaj xoom hla, yog li arcs pheej, ua rau melting, hluav taws kub, los yog tsis ua hauj lwm. Ib txwm siv DC-rated MCB zoo li CDADA DAB7-63.

Q2: Puas yog polarity tseem ceeb?

A2: Yog! DAB7-63 250V DC Miniature Circuit Breaker tau txhais cov tswv yim (hwj chim +/–) thiab cov zis (L + / L–) terminals. Rov qab polarity txo qis arc quenching efficiency thiab tej zaum yuav tsis muaj ntawv pov thawj kev nyab xeeb.

Q3: Dab tsi yog qhov txawv ntawm 1P, 2P, thiab 4P DC MCBs?

A3:

● 1P: Tiv thaiv ib tus neeg xyuas pib ntawm 250V DC (piv txwv li, kab zoo hauv av PV system)

● 2P: tawg ob qho tib si + thiab - ntawm 500V DC (floating systems)

● 4P: Rau 1000V DC cov hlua (cov khoom lag luam loj PV)

→ Ib txwm phim tus ncej suav rau koj qhov system voltage thiab av txheej txheem.

Q4: Nws puas tuaj yeem siv rau kev hloov pauv ntau zaus?

A4: Tsis yog - nws tau tsim los rau kev ua haujlwm tsis tu ncua (piv txwv li, kev saib xyuas). Rau kev hloov txhua hnub, siv DC contactor lossis hloov chaw thau khoom.

Q5: Vim li cas thiaj xaiv CDADA dua lwm hom DC MCB?

A5: CDADA muab:

● Muaj tseeb DC arc cuam tshuam tsim (tsis yog AC hloov kho)

● Daim ntawv pov thawj IEC + CCC

● Qhov taw qhia pom qhov pom tseeb

● Dav tam sim no ntau yam (1A–63A) kom meej qhov loj me

● Cov nqi sib tw nrog cov ntaub ntawv qhia ua lus Askiv
