MCCB ine Leakage Protection

Wedzera kuchengetedzeka kwemagetsi kupfuura kuwandisa uye kupfupi-sekiti chengetedzo neCDADA DAM1L Series MCCB ine Leakage Dziviriro yakasanganiswa yakaumbwa kesi yedunhu breaker ine yakavakirwa-mukati residual current (RCD/ELCB) mashandiro. Yakagadzirwa nenyanzvi yekugadzira Shanghai DADA Electric CO., LTD kune dzimwe nyika zviyero, iyi yekuvuza MCCB 4P inosanganisa yakakwirira-inoshanda kugovera magetsi nehupenyu- uye inoponesa moto pasi pekuona kukanganisa.

Yakarongerwa kubva ku10A kusvika ku500A pa400V/415V, inopa inogadziriswa yakasara inoshanda ikozvino (30mA-1000mA) uye inosarudzika kunonoka-inogonesa kuchengetedzwa kwakagadzirirwa kuchengetedzwa kwemunhu (≤30mA) kana kudzivirira moto (100mA-500mA +). Iine akawanda-chikamu magetsi emagetsi, inoramba ichishanda kunyangwe chikamu chimwe chikatadza kana voltage inodonha kusvika ku50V, ichiona kuvimbika kusingaenzaniswi muzvivakwa zvakakosha senge tunnels, makwiriro, nzvimbo dzekufambisa, uye zvidyarwa zvemaindasitiri.

Sei Sarudza CDADA MCCB ine Leakage Dziviriro?

★ Chokwadi Integrated Kuchengetedzwa

Kusiyana nekuwedzera-paRCD modules, iyo DAM1L ine yakavakirwa-mukati, fekitori-calibrated leakage dziviriro-inoona kurongeka kwakakwana uye kubvisa nyaya dzekuenderana.

★ Multi-Phase Simba reRCD Circuit

MaRCD ekutanga akakundikana kana chikamu chimwe chakarasika. Dhizaini yeCDADA inoshandisa nhanho dzese kusimbisa magetsi edziviriro, saka inoramba ichishanda kunyangwe panguva yekurasikirwa kwechikamu kana kuderera kwakanyanya.

★ Zvinangwa Zviviri Dziviriro mune Imwe Chishandiso

◆ 30mA: Inosangana neIEC zvinodiwa zvekudzivirira kuvhunduka kwevanhu

◆ 100mA-1000mA: Inodzivirira kupisa kwekudzivirira kupisa moto kubva kune zviduku, zvinoramba zvichikanganisa pasi.

★ Munda-Unogadziriswa kune Real-World Conditions

Fine-tune senitivity uye nguva kunonoka kudzivirira kugumburwa munzvimbo dzakanyorova (semuenzaniso, kugeza mota, mapurazi) uchichengetedza kuchengeteka.

★ Industrial-Giredhi Kuvimbika

Yakakwira yekutyora simba (H-mhando), yakasimba arc kupatsanurwa, uye IP20+ terminal kuchengetedza inoita kuti ive yakakodzera kune dzakaomarara kutengeserana uye maindasitiri marongero.

★ Global Compliance, Local Value

Certified for Europe (CE/CB), Nordic countries (SEMKO)—yakanakira mapurojekiti ekunze kunze—nemitengo inokwikwidza kubva kumugadziri akavimbika wekuChina.

★ Nzvimbo yedu yekugadzira inosimbiswa pasi pe ISO9001:2015 Quality Management System.

Typical Applications

Yepamusoro-Rise Residence: Muhoro mukuru kana pasi mapaneru (300mA yekudzikisa njodzi yemoto)

Tunnels & Subways: Yakakosha zvivakwa zvinoda kutadza-kuchengetedzeka kuvuza kuoneswa

Zvipatara & Zvikoro: 30mA dziviriro munzvimbo dzine mvura (maLab, zvimbudzi)

Industrial Plants: Motor feeders ine pasi pekutarisa kukanganisa

Nzvimbo dzekuvaka: Kugoverwa kwemagetsi kwenguva pfupi nekuchengetedzwa kwevashandi

FAQ

Q1: Ndeupi musiyano uripo pakati peyakajairwa MCCB uye MCCB ine leakage dziviriro?

A1: Yakajairwa MCCB inongodzivirira kubva pakuwandisa uye mapfupi maseketi. Iyo DAM1L inowedzera yakasara ikozvino (kudonha kwepasi) kucherechedzwa-kugumburwa kana ikozvino inodonha pasi (semuenzaniso, kuburikidza nemunhu kana yakakuvadzwa insulation), kudzivirira kuvhunduka kwemagetsi kana moto.

Q2: Ndingashandisa 100A MCCB RCD yekuzvidzivirira pachako here?

A2: Chete kana yakaiswa ku30mA. Iyo yakayerwa ikozvino (100A) inotsanangura mutoro wekutakura; iyo yakasara kugadzika (I△n) inotsanangura kuchengetedza basa. Nekudzivirira kwekuvhunduka, I△n inofanirwa kunge iri ≤30mA, zvisinei neIn.

Q3: Sei RCD redunhu richida akawanda-chikamu simba?

A3: Kana yakapihwa simba nechikamu chimwe chete, kutadza kwechikamu chimwe chete kwaizodzima kudzivirira kwekudonha. CDADA's multi-phase design inoita kuti RCD irambe ichishanda kunyange panguva yekurasikirwa kwechikamu kana kuderera kwemhepo (kusvika ku50V) -inokosha pakuenderera mberi kwekuchengeteka.

Q4: Iyo 4P kuvuza MCCB yakakodzera TT kana TN-S masisitimu?

A4: Hongu-yakagadzirirwa TT, TN-S, uye IT masisitimu. Iyo 4P dhizaini inopwanya ese matanho uye asina kwaakarerekera, yakakosha kune TT masisitimu uko kwaakarerekera asina kuvimbika kudzika kumusoro.

Q5: Sei uchisarudza CDADA pamusoro modular RCD + MCCB musanganiswa?

A5: CDADA DAM1L inopa:

● Diki yetsoka (yakabatanidzwa vs. midziyo miviri)

● Guaranteed coordination (hapana mismatch ngozi)

● Mutengo wakaderera & kuoma kwewaya

● Kuvimbika kwepamusoro (single sealed unit)

● Kugadziriswa kwepa-site hakugoneki ne-fixed-sensitivity RCDs
