Kev Piav Qhia Luv:

M4 series molded case circuit breaker, nws siv tau rau AC 50/60Hz, rated insulation voltage 690 V (M4-125 500V), rated operating voltage AC 690V lossis qis dua, rated operating current 12.5-1600A, rau kev faib hluav taws xob thiab tsis tshua muaj kev ua thiab tawg circuit hauv qhov xwm txheej ib txwm muaj. Cov circuit breakers muaj kev ua haujlwm ntawm kev tiv thaiv overload thiab luv circuit thiab undervoltage. Cov circuit breakers ua raws li tus qauv ntawm IEC60947-2. Cov circuit-breakers yog ob chav insulating (Hauv m = 250A lossis siab dua), lub voj voog tswj ntawm cov khoom siv tau teeb tsa sib nrug nrog lub voj voog tseem ceeb, thiab tsis tas yuav qhib lub hau ntawm lub circuit breaker thaum txhim kho cov khoom siv.
