Incazelo emfushane:

I-M4 series molded case circuit breaker, iyisekethe yayo esebenzayo ye-AC 50/60Hz, i-insulation voltage elinganisiwe engu-690 V (M4-125 500V), i-operating voltage elinganisiwe engu-AC 690V noma ngaphansi, i-operating current elinganisiwe engu-12.5-1600A, yokusabalalisa amandla kagesi kanye nokwenza okungajwayelekile kanye nokuphuka kwesekethe esimweni esijwayelekile. Ama-circuit breaker anikezwa umsebenzi wokuvikela ekucindezelweni ngokweqile kanye ne-short circuit kanye ne-undervoltage. Ama-circuit breaker ahambisana nezinga le-IEC60947-2. Ama-circuit-breaker afakwa i-insulation kabili (Ku-m=250A noma ngaphezulu), isekethe yokulawula yezesekeli ihlukaniswe nesekethe eyinhloko, futhi ayidingi ukuvula isembozo se-circuit breaker lapho ufaka izesekeli.
