Rudzi Rutsva CJRV-32X MPCB 25-32A Motor Protection Circuit Breaker

Tsananguro pfupi:

CJRV series AC Motor protection circuit breaker yakakodzera macircuit ane AC voltage inosvika 690V uye current inosvika 80A. LT inoshandiswa pakuremedza, kukundikana kwechikamu, kudzivirira circuit pfupi, uye kudzora kusingawanzoitiki kwemamota matatu-phase squirrel cage asynchronous. Inogona kushandiswa kudzivirira tambo dzekugovera uye kuchinja mutoro nguva nenguva, uye inogona kushandiswawo seisolator.

Mamiriro ekushanda nekuisa akajairika

Kureba kwenzvimbo yekuisa kazhinji hakupfuuri 2000m;
Muganho wakaderera wekupisa kwemhepo uri pakati nepakati hausi pasi pe -5 ℃, muganho wepamusoro hausi pamusoro pe+40℃, uye avhareji yemutengo wayo mukati memaawa makumi maviri nemana haipfuure+35 ℃;
Hunyoro hwemhepo hahufanirwe kudarika 90% (pa+25 ℃ ± 5 ℃)
Kusvibiswa kwenzvimbo yakapoteredza inhanho yechitatu yekusvibiswa;
Chikamu chekuisa chemutangisi ndechechikamu chekuisa lll;
Kurerekera pakati pechinhu chinotanga nepamusoro pekuisa kwakamira hakufanirwe kudarika ± 5 °;
Kugumburwa: CJRV-25 (X),CJRV-32 (X),CJRV-32H,CJRV-80:10A;
Maawa ekushanda akaongororwa: maawa ekushanda asingadzoreki, maawa masere ekushanda.
