Kuvaka uye Chimiro
- High pfupi-pfupi simba 10KA.
- Yakagadzirirwa kuchengetedza dunhu rinotakura hombe iripo kusvika ku125A.
- Bata chinzvimbo chiratidzo.
- Inoshandiswa se main switch mumba uye kuisirwa kwakafanana.
- Kuderera kwesimba rekushandisa uye yakakosha kuchengetedza simba
- Kuvandudza kugadzirwa uye ecological nharaunda uye economize kugadzirisa kwemidziyo
- Overload protection
- Vhara nekukurumidza
- High breaking capacity
Yakachengeteka uye Yakavimbika
- Otomatiki kuvhara ine shoma yemagetsi spark yekuwedzera hupenyu hwekushanda hwemidziyo
- Dhigirii redziviriro: IP20-Kuvimbisa kubatana kwakachengeteka uye kwakavimbika
- Stain-resistance: Level 3-Kudzivirira guruva uye conductive kusvibiswa

Chii chinonzi MCB?
Miniature Circuit Breaker (MCB) imhando yedunhu rinotyora iro diki muhukuru.Inobva yacheka kutenderera kwemagetsi panguva ipi zvayo isina kunaka mumagadzirirwo emagetsi ekupa magetsi, zvakadai sekuwedzera kwepamusoro kana kuti pfupi-circuit current.Kunyangwe mushandisi anogona kuseta zvakare MCB, fuse inogona kuona aya mamiriro, uye mushandisi anofanira kuitsiva.
Kana MCB iri pasi pekuenderera mberi-ikozvino, bimetallic strip inopisa uye inokotama.Electromechanical latch inoburitswa apo iyo MCB inobvisa bi-metallic strip.Kana mushandisi abatanidza iyi electromechanical clasp kune inoshanda michina, inovhura iyo microcircuit breaker contacts.Nekuda kweizvozvo, zvinokonzeresa iyo MCB kudzima uye kumisa kuyerera kwazvino.Mushandisi anofanira kushandura ega paMCB kuti adzorere kuyerera kwazvino.Mudziyo uyu unodzivirira kukanganiswa kunokonzerwa nekuwedzeredza ikozvino, kuwandisa, uye mapfupi maseketi.
