Iyo ndeye electro-mechanical mune zvakasikwa.Chinonyanya kukosha apa ndechekuti:
1. inogona kubatanidzwa newaya munzira ipi neipi.
2.Inoenderana neIEC 61009-2-1 (mains voltage yakazvimirira RCBO), Iyo ine electro-mechanical release iyo inoshanda zvakachengeteka kunyange pasina magetsi ekupa kana mutsara wemagetsi pasi pe50V.
3.Type -A: Inodzivirira kubva kumhando dzakakosha dzekusarira pulsating DC iyo isina kukwenenzverwa.
4.Inopa dziviriro pamusoro pepasi kukanganisa / kuputika ikozvino, pfupi-circuit, overload, uye basa rekuzviparadzanisa.
5.Inopa kudzivirirwa kunopindirana pakusangana kwakananga nemuviri wemunhu Zvinobudirira kuchengetedza zvigadzirwa zvemagetsi kubva pakutadza kwekudzivirira.
6.Inopa kuchengetedzwa kwakazara kune dzimba uye zvekutengesa kugovera masisitimu.
7.high breaking capacity kusvika 10ka.more yakachengeteka.
