Chotsekera chaching'ono cha RDB8A-63 (chomwe chimatchedwa chotsekera chaching'ono), chomwe chimagwiritsidwa ntchito makamaka mu mizere yogawa chitetezo ndi AC 50Hz, voteji yogwira ntchito yovomerezeka yosapitirira 400V, mphamvu yamagetsi yovomerezeka yosapitirira 63A, ndi mphamvu yamagetsi yocheperako yosapitirira 6000A; ingagwiritsidwenso ntchito pamagetsi a DC unipolar osapitirira 110V, mitengo iwiri yosapitirira 220V, mphamvu yamagetsi ya DC yosapitirira 63A, mphamvu yamagetsi yocheperako ya DC yosapitirira 6000A mu mizere yogawa yoteteza; imagwiritsidwa ntchito polumikizira pafupipafupi, kuswa ndi kusinthana kwa mizere, ndi overload, ntchito yoteteza yamagetsi afupi. Nthawi yomweyo, ili ndi ma module amphamvu othandizira, monga ma contact othandizira, ma contact ndi alamu, shunt release, undervoltage release, remote trip control ndi ma module ena.
1. Njira yotsimikizika yogwirira ntchito
2. Kabuku kakang'ono, mphamvu yayikulu
3. Mphamvu ya mawaya amphamvu kwambiri
4.Kuteteza kwabwino pakati pa magawo
5. Kuyendetsa bwino kwambiri
6. Kukwera kwa kutentha kochepa ndi kugwiritsa ntchito mphamvu
Deta yaikulu yaukadaulo
Makhalidwe a kugwedezeka kwa mphamvu yamagetsi yochulukirapo: Pansi pa mikhalidwe yabwinobwino yokhazikitsira ndi kutentha koyenera (30-35)°C
Makhalidwe okhudzika a chosokoneza ma circuit akukwaniritsa zofunikira zomwe zili mu Table 1.
Mphamvu yogawa mphamvu ya circuit breaker yocheperako ikuwonetsedwa mu Table 2.
