Incazelo emfushane:

Uchungechunge lwe-M4 olubunjwe i-circuit breaker, isifunda salo esisebenzayo se-AC 50/60Hz,i-voltage elinganisiwe yokufaka engu-690 V(M4-125 500V), ikalwe nge-voltage yokusebenza engu-AC 690V noma ngezansi, ikalwe ukusebenza kwamanje okungu-12.5-1600A, ukusabalalisa amandla kagesi nokungajwayelekile esimweni sokwephulwa kwesekethe. Ama-circuitbrea kers anikezwa umsebenzi wokuvikela ekulayisheni ngokweqile kanye nesekethe emfishane kanye ne-undervoltage. Ama-circuit breakers ahambisana nezinga le-IEC60947-2.Ama-circuit-breaker afaka i-double insulating (Ku-m=250A noma ngaphezulu), isifunda sokulawula sezesekeli sihlukaniswa nesifunda esikhulu, futhi asidingi ukuvula ikhava ye-circuit breaker lapho kufakwa izesekeli.
