Khoom Taw Qhia

RDB8A-63 me me Circuit Court breaker (tom qab no hu ua Circuit Court breaker), feem ntau yog siv nyob rau hauv cov kev tiv thaiv tis kab nrog AC 50Hz, rated ua hauj lwm voltage tsis tshaj 400V, rated tam sim no tsis tshaj 63A, thiab ntsuas luv luv Circuit Court breaking peev tsis tshaj 6000A;Nws kuj tuaj yeem siv rau DC voltage unipolar tsis tshaj 110V, ob tug ncej tsis tshaj 220V, ntsuas DC tam sim no tsis tshaj 63A, ntsuas DC luv-circuit breaking peev tsis tshaj 6000A hauv kev tiv thaiv kab;siv rau kev sib txuas tsis tu ncua, tawg thiab hloov ntawm cov kab, nrog rau kev tshaj tawm, luv Circuit Court tiv thaiv muaj nuj nqi.Nyob rau tib lub sijhawm, nws muaj lub zog pabcuam kev ua haujlwm zoo, xws li kev pabcuam pabcuam, kev sib cuag nrog lub tswb ntsuas, shunt tso tawm, tso tawm undervoltage, kev tswj chaw taws teeb thiab lwm yam modules.

Nta

1.Process guaranteed kev ua tau zoo

2.Small ntim, muaj peev xwm loj

3.Super-muaj zog thaiv muaj peev xwm

4.Kev rwb thaiv tsev zoo ntawm cov theem

5.Super-muaj zog conductivity

6. Tsawg kub nce thiab lub zog noj

RDB8A series Circuit Court breaker yog cov khoom siv hluav taws xob hluav taws xob uas muaj peev xwm txwv tam sim no thiab muaj kev ntseeg siab tshwj xeeb uas tsim los ntawm People Electric rau kev lag luam kev sib txuas lus.Feem ntau yog siv hauv cov khoom siv hluav taws xob xws li cov khoom loj, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov khoom siv sab nraum zoov hauv kev lag luam kev sib txuas lus.Cov khoom ua raws li: GB / T 10963.2 tus qauv.

Cov ntaub ntawv tseem ceeb

Overcurrent tripping yam ntxwv: Raws li kev teeb tsa ib txwm muaj thiab siv ambient kub (30-35) ° C

lub overcurrent tripping yam ntxwv ntawm Circuit Court breaker ua tau raws li qhov yuav tsum tau muaj nyob rau hauv Table 1.

Qhov ntsuas luv luv-circuit breaking peev xwm ntawm Circuit Court breaker yog qhia nyob rau hauv Table 2.
