MCCB

ELM1 dzakatevedzana Molded Case Circuit Breaker (MCCB)

ELM1 MCCB inotevedzera IEC 60947-2, ichipa dziviriro yemuindasitiri ye63A–1250A applications (modheru: ELM1-160/250/400/630/1250) mumagadzirirwo emapango e3P/4P ane mapango emhando yeA/D/N. Zvinhu zvikuru zvinosanganisira 690V insulation voltage, 400V operational voltage (kusvika ku690V), uye 100kA break capacity yakakwira (ELM1-1250). Inobatanidza thermal-magnetic trips neoptional intelligent trips, verified inverse-time protection (≤20s at 7.2In cold). Dhizaini yemodular inotsigira plug-in, motor-driven, kana rotary-handle operation, nekugona kuwedzera kuburikidza ne shunt releases uye assistant contacts. Yakasimba, inogona kushandiswa zvakasiyana-siyana, uye yakavimbika, inokodzera zvinodiwa zvakasiyana-siyana zvekudzivirira maindasitiri.

Tsananguro yeChigadzirwa

ELM1 Series MCCB inoshandisa tekinoroji yepamusoro yepasi rose, inoenderana zvizere neIEC 60947-2, uye yakagadzirwa kuti igoverwe simba remaindasitiri uye dziviriro yemota. Inofukidza ma currents akarongwa kubva pa63A kusvika pa1250A (mamodheru: ELM1-160/200/400/630/800/1250) ine 3P/4P configurations (4P inosanganisira A/B/C/D N-pole types), inoita kuti ishandiswe zvakasiyana-siyana. Zvinhu zvakakosha zvinosanganisira 690V rated insulation voltage, 400V AC operational voltage (inogona kuwedzerwa kusvika pa690V), uye breaking capacity inosvika 100kA (semuenzaniso, ELM1-1250), inotsigira 50/60Hz AC grids yekuchinja circuit nguva nenguva uye kudzora mota.

Inobatanidza mayuniti ekufamba nemhepo ane thermal-magnetic uye mayuniti ekufamba nemhepo ane hunyanzvi kuti adzivirire mhepo zvakanyanya. Zvinhu zvakakosha pakushanda zvinosanganisira inverse-time action (semuenzaniso, kukurumidza kudonha pa7.2×In mumamiriro ekunze anotonhora), rated non-trip current ye1.05In (inobata ≥2h), uye trip threshold trip threshold pa1.30In. Breaking capacity scales nemamodheru: base variants (semuenzaniso, ELM1-160) inopa 50kA, nepo mamodheru epamusoro (semuenzaniso, ELM1-1250) achisvika 100kA@400V.

Nhevedzano iyi ine dhizaini yepamusoro-soro, inotsigira mashandiro eplug-in, motor-driven, uye rotary-handle, ine kugona kuwedzera kuburikidza nekuburitsa shunt, kuburitsa undervoltage, uye assistant contacts. Chimiro chayo chakabatana (zviyero pamatafura eparameter) chinogadzirisa nzvimbo yemapaneru, ichiwedzerwa nemhinduro dzakajairwa dzekuisa njanji. Yakapihwa chitupa chepasi rose, ELM1 Series yakagadzirirwa maswitchboard eindasitiri uye masisitimu ekuparadzira simba, ichipa mashandiro akavimbika munzvimbo dzinoda simba.

Kushandiswa

ELM1 series molded case circuit breaker ndeimwe yezvigadzirwa zvakagadzirwa uye zvinogadzirwa nekushandisa tekinoroji yepamusoro-soro yepasi rose. Inowanikwa ne rated insulating voltage 690V uye inoshandiswa pa circuit ye AC50/60Hz, rated operating voltage AC 400V (kana pasi), rated operating current inosvika 1250A yekuchinja-chinja uye kutanga kwema motors nguva nenguva. Zvigadzirwa izvi zvinoenderana neIEC60947-2 standard.
