I-MCCB enokuvikelwa kokuvuza

Thuthukisa ukuphepha kukagesi ngaphezu kokugcwala kakhulu kanye nokuvikela isiyingi esifushane nge-CDADA DAM1L Series MCCB ene-Leakage Protection isiqephu sesekesi esihlanganisiwe esihlanganisiwe esinokusebenza kwensalela eyakhelwe ngaphakathi (RCD/ELCB). Idizayinelwe umkhiqizi ochwepheshe i-Shanghai DADA Electric CO., LTD kuya kuzindinganiso zamazwe ngamazwe, lokhu kuvuza kwe-MCCB 4P kuhlanganisa ukusatshalaliswa kwamandla okusebenza okuphezulu nokutholwa kwamaphutha komhlaba okusindisa ukuphila nokusindisa umlilo.

Ilinganiselwe ukusuka ku-10A ukuya ku-500A ku-400V/415V, inikeza ukusebenza kwensalela elungisekayo (30mA–1000mA) kanye nokulibaziseka kwesikhathi ongakukhetha—okuvumela ukuvikelwa okulungiselelwe ukuphepha komuntu siqu (≤30mA) noma ukuvimbela umlilo (100mA–500mA+). Ngama-elekthronikhi asebenza ngezigaba eziningi, ahlala esebenza noma ngabe isigaba esisodwa sihluleka noma amandla kagesi ehla aze afike ku-50V, okuqinisekisa ukwethembeka okungenakuqhathaniswa kwingqalasizinda ebalulekile njengamahubhe, izindawo eziphakeme, izindawo zokuhamba, nezitshalo zezimboni.

Kungani Khetha i-CDADA MCCB enokuvikelwa kokuvuza?

★ Ukuphepha Okudidiyelwe Kweqiniso

Ngokungafani namamojula e-RCD engeziwe, i-DAM1L inokuvikelwa kokuvuza okwakhelwe ngaphakathi, okulinganiselwe efekthri—iqinisekisa ukusebenzisana okuphelele nokuqeda izinkinga zokuhambisana.

★ Multi-Phase Power for RCD Circuit

Ama-RCD angaphambi kwesikhathi ahlulekile uma kulahleka isigaba esisodwa. Idizayini ye-CDADA isebenzisa zonke izigaba ukuze inike amandla izinto zikagesi ezivikelayo, ngakho iqhubeka isebenza ngisho naphakathi nokulahlekelwa kwesigaba noma ukungasebenzi kahle kwamandla.

★ Imigomo Yokuvikela Ekabili Kudivayisi Eyodwa

◆ 30mA: Ihlangabezana nezimfuneko ze-IEC zokuvikela ukushaqeka komuntu siqu

◆ 100mA–1000mA: Ivimbela imililo ewohlokayo evela kumaphutha amancane, aqhubekayo

★ Field-Adjustable for Real-World Conditions

Ukuzwela kwe-Fine-tune kanye nokulibaziseka kwesikhathi ukuze kugwenywe ukuphazamiseka ezindaweni ezimanzi (isb., ukuwashwa kwezimoto, amapulazi) ngenkathi kugcinwa ukuphepha.

★ Ukwethenjelwa kwe-Industrial-Grade

Umthamo omkhulu wokuphuka (uhlobo lwe-H), ukuhlukaniswa kwe-arc okuqinile, nokuvikelwa kwetheminali ye-IP20+ kuyenza ifanelekele izilungiselelo zezentengiso nezimboni ezinokhahlo.

★ Ukuthobela Umhlaba Wonke, Inani Lendawo

Igunyazwe i-Europe (CE/CB), amazwe ase-Nordic (SEMKO)—ilungele amaphrojekthi okuthumela ngaphandle—ngamanani ancintisanayo avela kumkhiqizi othembekile wase-China.

★ Isikhungo sethu sokukhiqiza sigunyazwe ngaphansi kwe-ISO9001:2015 Quality Management System.

Indawo yokuhlala esezingeni eliphezulu: Umtholi omkhulu noma amaphaneli aphansi (300mA yokunciphisa ubungozi bomlilo)

Amahubhu nezitimela ezihamba ngaphansi: Ingqalasizinda ebalulekile edinga ukutholwa kokuvuza okuhlulekayo

Izibhedlela Nezikole: Ukuvikelwa okungu-30mA ezindaweni ezimanzi (amalebhu, izindlu zangasese)

Izitshalo Zezimboni: Iziphakeli zezimoto ezinokuqapha amaphutha aphansi

Izindawo Zokwakha: Ukusabalalisa amandla esikhashana ngokuvikelwa kwabasebenzi

FAQ

Q1: Uyini umehluko phakathi kwe-MCCB ejwayelekile ne-MCCB enokuvikelwa kokuvuza?

I-A1: I-MCCB ejwayelekile ivikela kuphela ekulayisheni ngokweqile namasekhethi amafushane. I-DAM1L yengeza ukutholwa kwensalela yamanje (ukuvuza komhlaba)—ukukhubeka lapho kuvuza kwamanje phansi (isb., ngomuntu noma okokuhlukanisa okonakele), ukuvimbela ukushaqeka kukagesi noma umlilo.

Q2: Ngingakwazi ukusebenzisa i-100A MCCB RCD ukuze ngivikelwe?

I-A2: Kuphela uma isethelwe ku-30mA. Isilinganiso samanje (100A) sichaza umthamo wokulayisha; isilungiselelo esisele (I△n) sichaza umsebenzi wokuphepha. Ngokuvikela ukushaqeka, i-I△n kufanele ibe ngu-≤30mA, kungakhathaliseki ukuthi i-In.

Q3: Kungani isifunda se-RCD sidinga amandla ezigaba eziningi?

I-A3: Uma inikwa amandla yisigaba esisodwa kuphela, ukwehluleka kwesigaba esisodwa kuzokhubaza ukuvikela ukuvuza. Idizayini yezigaba eziningi ze-CDADA iqinisekisa ukuthi i-RCD ihlala isebenza ngisho naphakathi kokulahlekelwa kwesigaba noma i-voltage ephansi (ehle iye ku-50V)—okubalulekile ukuqhubeka kokuphepha.

Q4: Ingabe i-MCCB yokuvuza kwe-4P ifanele amasistimu e-TT noma e-TN-S?

A4: Yebo—yenzelwe i-TT, TN-S, kanye nezinhlelo ze-IT. Idizayini ye-4P iphula zonke izigaba futhi ingathathi hlangothi, ibalulekile kumasistimu e-TT lapho ukungathathi hlangothi kungasekelwenga ngokuthembekile phezulu komfula.

I-Q5: Kungani ukhetha i-CDADA ngaphezu kwenhlanganisela ye-RCD + MCCB eyimojula?

I-A5: Izipesheli ze-CDADA DAM1L:

● Unyawo oluncane (okuhlanganisiwe uma kuqhathaniswa namadivayisi amabili)

● Ukuxhumana okuqinisekisiwe (abukho ubungozi bokungafani)

● Izindleko eziphansi nokuba yinkimbinkimbi kwezintambo

● Ukuthembeka okuphezulu (iyunithi evaliwe eyodwa)

● Ukulungiswa kwendawo akunakwenzeka ngama-RCD okuzwela okungaguquki
