Mashandisirwo

MaCJW1 series akangwara epasi rese macircuit breakers anogona kushandiswa nefir achidzora mambure ekugovera magetsi mashoma uye achichengetedza kuchengetedzeka kwawo. Kuisa mumapaneru ekugovera magetsi mashoma, inoshanda sechishandiso chikuru chekuchengetedza. Hunhu hwayo hwehunyanzvi hwasvika padanho repamusoro repasi rose rezvigadzirwa zvakadaro muma1990. Inokodzera circuit yeAC 50Hz, vhoriyamu yakayerwa i660V (690V) kana pasi, vhoriyamu yemagetsi i400A-6300A.

Mutongi akangwara akasiyana-siyana anopa mabasa akasiyana-siyana.

Maputsi aya anotevedzera zvinodiwa nezvinodiwa zvinotevera, IEC 60947-2, GB14048.2-2001.
