I-MCCB enoKhuseleko lokuvuza

Ukuphucula ukhuseleko lombane ngaphaya komthwalo ogqithisiweyo kunye nokukhusela i-short-circuit kunye ne-CDADA DAM1L Series MCCB kunye noKhuseleko lwe-Leakage i-molded leakage circuit breaker kunye ne-built-in residual current (RCD / ELCB) ukusebenza. Eyilwe ngumvelisi oqeqeshiweyo we-Shanghai DADA Electric CO., LTD ukuya kwimigangatho yamazwe ngamazwe, oku kuvuza kwe-MCCB 4P idibanisa ukuhanjiswa kwamandla okusebenza okuphezulu kunye nobomi kunye nokugcinwa kwempazamo emhlabeni.

Ilinganiswe ukusuka kwi-10A ukuya kwi-500A kwi-400V / 415V, inika i-residual residual current current (30mA-1000mA) kunye nokulibaziseka kwexesha lokuzikhethela-ukuvumela ukukhuselwa okulungiselelwe ukhuseleko lomntu (≤30mA) okanye ukukhusela umlilo (100mA-500mA +). Ngee-electronics ezinezigaba ezininzi, zihlala zisebenza nokuba isigaba esinye siyasilela okanye i-voltage yehla ukuya kwi-50V, iqinisekisa ukuthembeka okungahambelaniyo kwiziseko ezingundoqo ezifana neetonela, ukuphakama okuphezulu, iindawo zokuhamba, kunye nezityalo zemizi-mveliso.

Kutheni Khetha i-CDADA MCCB enoKhuseleko lokuvuza?

★ Ukhuseleko oluDityanisiweyo lwenene

Ngokungafaniyo neemodyuli ze-RCD ezongeziweyo, i-DAM1L ine-built-in, i-factory-calibrated ukukhuselwa kokuvuza-ukuqinisekisa ukulungelelaniswa okugqibeleleyo kunye nokuphelisa imiba ehambelanayo.

★ Amandla amanqanaba amaninzi kwi-RCD Circuit

Ii-RCD zangaphambili zasilela ukuba isigaba esinye silahlekile. Uyilo lwe-CDADA lusebenzisa zonke izigaba ukunika amandla ukhuseleko lwe-elektroniki, ngoko luhlala lusebenza nangexesha lokulahleka kwesigaba okanye ukungabikho kwamandla.

★ Iinjongo zoKhuseleko oluBini kwisixhobo esinye

◆ 30mA: Idibana neemfuno ze-IEC zokhuseleko lomntu kumntu

◆ 100mA–1000mA: Ikhusela ukuthotywa komlilo kwimililo encinci, eqhubekayo emhlabeni.

★ Field-Adjustable for Real-World Conditions

I-Fine-tune sensitivity kunye nokulibaziseka kwexesha ukuphepha ukuphazamiseka kokuhamba kwiindawo ezimanzi (umzekelo, ukuhlamba iimoto, iifama) ngelixa ugcina ukhuseleko.

★ Ukuthembeka kweBanga loShishino

Umthamo ophezulu wokuqhawula (uhlobo lwe-H), ukuhlukana kwe-arc eyomeleleyo, kunye ne-IP20 + yokukhusela i-terminal yenza ukuba ifaneleke kwimimiselo enzima yezorhwebo kunye nezoshishino.

FAQ

I-Q1: Uthini umahluko phakathi kwe-MCCB eqhelekileyo kunye ne-MCCB enokukhusela ukuvuza?

I-A1: I-MCCB eqhelekileyo ikhusela kuphela ekugqithiseni kunye neesekethe ezimfutshane. I-DAM1L yongeza i-residual current (ukuvuza komhlaba) ukufumanisa-i-tripping xa ukuvuza kwangoku kumhlaba (umzekelo, ngomntu okanye i-insulation eyonakalisiweyo), ukukhusela ukutshatyalaliswa kombane okanye umlilo.

I-Q2: Ngaba ndingasebenzisa i-100A MCCB RCD yokukhusela umntu?

A2: Kuphela ukuba imiselwe kwi-30mA. Ireyithingi yangoku (100A) ichaza umthamo womthwalo; useto olushiyekileyo (I△n) luchaza umsebenzi wokhuseleko. Ukukhusela umothuko, I△n kufuneka ibe ≤30mA, nokuba i-In.

I-Q3: Kutheni isekethe ye-RCD idinga amandla amanqanaba amaninzi?

I-A3: Ukuba inikwe amandla ngesigaba esinye kuphela, ukungaphumeleli kwesigaba esinye kuya kukhubaza ukukhuselwa kokuvuza. I-CDADA yoyilo lwezigaba ezininzi luqinisekisa ukuba i-RCD ihlala isebenza nangexesha lokulahleka kwesigaba okanye i-voltage ephantsi (ukuya kwi-50V) -ibaluleke kakhulu ekuqhubekeni kokhuseleko.

I-Q4: Ngaba i-4P yokuvuza i-MCCB ifanelekile kwiinkqubo ze-TT okanye ze-TN-S?

A4: Ewe-yenzelwe iTT, TN-S, kunye neenkqubo ze-IT. Uyilo lwe-4P luphula zonke izigaba kunye nokungathathi hlangothi, okuyimfuneko kwiinkqubo ze-TT apho ukungathathi hlangothi kungasekelwanga ngokuthembekileyo phezulu.

I-Q5: Kutheni ukhetha i-CDADA ngaphezu kweemodyuli ze-RCD + MCCB indibaniselwano?

A5: CDADA DAM1L inikeza:

● Unyawo oluncinci (oludityanisiweyo vs. izixhobo ezibini)

● Ulungelelwaniso oluqinisekisiweyo (akukho mngcipheko ungafaniyo)

● Ixabiso eliphantsi kunye nobunzima bocingo

● Ukuthembeka okuphezulu (iyunithi enye etywiniweyo)

● Ukulungelelaniswa kwendawo akukwazeki ngee-RCD zobuthathaka obusisigxina
