MCCB yokhala ndi Chitetezo cha Leakage

Limbikitsani chitetezo chamagetsi kupitilira kulemetsa komanso chitetezo chachifupi ndi CDADA DAM1L Series MCCB yokhala ndi Kutayikira kwachitetezo chophatikizika chophatikizika chophatikizika chokhala ndi magwiridwe antchito otsalira (RCD/ELCB). Zopangidwa ndi katswiri wopanga Shanghai DADA Electric CO., LTD malinga ndi miyezo yapadziko lonse lapansi, kutayikira kumeneku kwa MCCB 4P kumaphatikiza kugawa kwamphamvu kwamphamvu ndi kuzindikira kwapadziko lapansi komanso kupulumutsa moto.

Yoyezedwa kuchokera ku 10A mpaka 500A pa 400V/415V, imapereka zotsalira zotsalira zomwe zikugwira ntchito panopa (30mA-1000mA) ndi kuchedwa kwa nthawi yosankha-kuteteza chitetezo chaumwini (≤30mA) kapena kupewa moto (100mA-500mA +). Ndi magetsi opangidwa ndi magawo ambiri, imagwirabe ntchito ngakhale gawo limodzi litalephera kapena kutsika kwamagetsi mpaka 50V, kuwonetsetsa kudalirika kosayerekezeka pamakina ofunikira monga ma tunnel, malo okwera, malo oyendera, ndi mafakitale aku mafakitale.

Why Choose CDADA MCCB with Leakage Protection?

★ Chitetezo Chophatikizana Choona

Mosiyana ndi ma module a RCD owonjezera, DAM1L ili ndi chitetezo chokhazikika, cholumikizidwa ndi fakitale-kuwonetsetsa kulumikizana kwabwino ndikuchotsa zovuta zofananira.

★ Multi-Phase Power ya RCD Circuit

Ma RCD oyambirira analephera ngati gawo limodzi linatayika. Mapangidwe a CDADA amagwiritsa ntchito magawo onse kuti apatse mphamvu zamagetsi zoteteza, motero amapitilirabe kugwira ntchito ngakhale pakutayika kwa gawo kapena kuwonongeka kwakukulu.

★ Zolinga Zoteteza Pawiri Pachipangizo Chimodzi

◆ 30mA: Imakwaniritsa zofunikira za IEC pachitetezo chamunthu

◆ 100mA-1000mA: Imateteza kutentha kwamoto kuchokera ku zolakwika zazing'ono, zokhazikika pansi

★ Field-Adjustable for Real-World Conditions

Kumveka bwino kwa nyimbo ndi kuchedwa kwa nthawi kuti mupewe kugwedezeka m'malo onyowa (monga malo ochapira magalimoto, mafamu) posunga chitetezo.

★ Kudalirika kwa Industrial-Grade

High breaking capacity (H-mtundu), kupatukana kolimba kwa arc, ndi IP20+ terminal chitetezo zimapangitsa kuti ikhale yoyenera pazamalonda ndi mafakitale.

★ Global Compliance, Local Value

Wotsimikizika ku Europe (CE/CB), mayiko a Nordic (SEMKO) -oyenera kugulitsa katundu kunja - ndi mitengo yampikisano yochokera kwa wopanga odalirika waku China.

★ Malo athu opangira zinthu ndi ovomerezeka pansi pa ISO9001:2015 Quality Management System.

Ntchito Zofananira

Nyumba Yokwera Kwambiri: Opeza ndalama zambiri kapena mapanelo apansi (300mA kuti achepetse chiopsezo chamoto)

Tunnels & Subways: Zomangamanga zofunikira zomwe zimafuna kuzindikirika kosalephera kutayikira

Zipatala & Sukulu: Chitetezo cha 30mA m'malo onyowa (ma lab, zimbudzi)

Industrial Plants: Ma feed a ma motor okhala ndi kuyang'anira zolakwika za pansi

Malo Omanga: Kugawa mphamvu kwakanthawi ndi chitetezo cha ogwira ntchito

FAQ

Q1: Kodi pali kusiyana kotani pakati pa MCCB yokhazikika ndi MCCB yokhala ndi chitetezo chotuluka?

A1: MCCB yodziwika bwino imateteza kuchulukira komanso mabwalo amfupi. DAM1L imawonjezera kudziwika kotsalira (kutuluka kwa dziko lapansi)-kugwedezeka pamene madzi akutuluka pansi (mwachitsanzo, kupyolera mwa munthu kapena zowonongeka zowonongeka), kuteteza kugwedezeka kwa magetsi kapena moto.

Q2: Kodi ndingagwiritse ntchito 100A MCCB RCD podziteteza?

A2: Pokhapokha ngati akhazikitsidwa ku 30mA. Zomwe zidavoteredwa pano (100A) zimatanthawuza kuchuluka kwa katundu; zotsalira zotsalira (I△n) zimatanthauzira chitetezo. Pachitetezo chodzidzimutsa, I△n iyenera kukhala ≤30mA, mosasamala kanthu za In.

Q3: Chifukwa chiyani dera la RCD limafunikira mphamvu zamagawo angapo?

A3: Ngati ikuyendetsedwa ndi gawo limodzi lokha, kulephera kwa gawo limodzi kungalepheretse chitetezo chotuluka. Mapangidwe amtundu wa CDADA amatsimikizira kuti RCD imakhalabe yogwira ntchito ngakhale panthawi yotayika kapena kuchepa kwa magetsi (mpaka ku 50V) -yofunikira kuti chitetezo chipitirizebe.

Q4: Kodi kutayikira kwa 4P MCCB ndikoyenera machitidwe a TT kapena TN-S?

A4: Inde, idapangidwira TT, TN-S, ndi IT. Mapangidwe a 4P amaphwanya magawo onse komanso osalowerera ndale, ofunikira pamakina a TT pomwe ndale sizokhazikika kumtunda.

Q5: Why choose CDADA over modular RCD + MCCB combinations?

A5: CDADA DAM1L imapereka:

● Kachidindo kakang'ono (zophatikizana ndi zida ziwiri)

● Kugwirizana kotsimikizika (palibe chiopsezo chosagwirizana)

● Kutsika mtengo & zovuta zamawaya

● Kudalirika kwakukulu (gawo losindikizidwa limodzi)

● Kusintha kwapamalo sikutheka ndi ma RCD okhazikika
