Taw qhia
Qhia txog EA7 series 300A 400A 3PHASE Thermal MCCB (Molded Case Circuit Breakers), tshwj xeeb tsim rau AC fais fab kev faib tes hauj lwm ua haujlwm ntawm 50/60Hz. Cov MCCBs no, muaj kev tiv thaiv kev ruaj ntseg tiv thaiv overload, luv luv Circuit Court, thiab nyob rau hauv voltage tej yam kev mob thaum zoo faib hluav taws xob zog.
EA7 series 300A 400A 3PHASE Thermal MCCB muaj qhov ntsuas hluav taws xob rwb thaiv tsev ntawm 1000V, ua rau lawv muaj peev xwm tuav kev khiav hauj lwm voltages txog 400V. Qhov no ua kom muaj kev sib raug zoo nrog ntau yam ntawm cov tshuab hluav taws xob uas muaj nyob hauv kev lag luam thiab kev lag luam.
Nrog lawv cov peev xwm nqa tam sim no siab txog li 400A, EA7 series 300A 400A 3PHASE Thermal MCCB muab kev tiv thaiv zoo tiv thaiv hluav taws xob. Lawv tau nruab nrog cov txheej txheem thermal mus ncig uas cuam tshuam tam sim ntawm Circuit Court thaum kuaj pom qhov txawv txav tam sim no lossis qhov voltage, tiv thaiv kev puas tsuaj thiab ua kom muaj kev nyab xeeb ntawm cov hluav taws xob.
Tsim kom muaj kev ruaj khov, EA7 series 300A 400A 3PHASE Thermal MCCB muaj peev xwm tiv taus qhov kev xav tau ntawm kev hloov pauv tsis tu ncua thiab lub cev muaj zog pib ua haujlwm. Lawv xa cov kev ua tau zoo ib yam nyob rau lub sijhawm, ua rau lawv haum rau ntau yam kev siv hauv AC fais fab kev sib txuas.
Hauv cov ntsiab lus, EA7 series 300A 400A 3PHASE Thermal MCCB yog cov khoom tseem ceeb rau AC fais fab kev faib tes hauj lwm. Nrog rau lawv cov hluav taws xob hluav taws xob siab, kev sib raug zoo nrog cov kev khiav hauj lwm sib txawv, thiab muaj peev xwm los tswj cov khoom siv tam sim no, cov hluav taws xob hluav taws xob no tau faib hluav taws xob zoo thaum muab kev tiv thaiv txhim khu kev qha. Lawv cov kav ntev thiab kev ua tau zoo ib yam ua rau lawv muaj kev ntseeg siab rau kev ua kom muaj kev nyab xeeb thiab ua haujlwm ntawm cov tshuab hluav taws xob hauv ntau qhov chaw lag luam thiab kev lag luam.
