RDB8A-63 miniature circuit breaker (inozonzi circuit breaker), inonyanya kushandiswa mumitsetse yekudzivirira ine AC 50Hz, volteji yekushanda yakayerwa isingapfuure 400V, current yakayerwa isingapfuure 63A, uye current breaking capacity yakayerwa isingapfuure 6000A; inogona zvakare kushandiswa kune DC voltage unipolar isingapfuure 110V, matanda maviri asingapfuure 220V, current yakayerwa DC isingapfuure 63A, current breaking capacity yakayerwa DC isingapfuure 6000A mumitsetse yekudzivirira; inoshandiswa pakubatanidza nguva nenguva, kutyoka nekuchinjana kwemitsetse, ine overload, Short circuit protection function. Panguva imwe chete, ine ma assistant function modules ane simba, akadai se assistant contacts, contacts with alarm indication, shunt release, undervoltage release, remote trip control nedzimwe modules.

Zvinhu zvirimo

1. Maitiro akavimbiswa mashandiro

2.Small volume, hombe kugona

3. Kukwanisa kupinza waya kwakasimba kwazvo

4.Kudzivirira kwakanaka pakati pezvikamu

5. Kufambisa kwakasimba kwazvo

6.Kukwira kwekupisa kwakaderera uye kushandiswa kwesimba

Ruzivo rukuru rwehunyanzvi

Hunhu hwekugumburwa kwemvura yakawandisa: Pasi pemamiriro ezvinhu akajairwa ekuisa uye tembiricha yekunze (30-35)°C

hunhu hwekugumburwa kwecircuit breaker hunosangana nezvinodiwa muTafura 1.

Kukwanisa kuputsa circuit short-circuit kwecircuit breaker kwakaratidzwa muTafura 2.
