Inkcazo kunye noLungiselelo

POLE: 2P, 4P Ue: 230/400V
Kwi: 5-15A(5, 10, 15)A;
10-30A(10, 20, 30)A;
10-30A(10, 15, 20, 25, 30)A;
30-60A(30, 45, 60)A;
60-90A(60, 75, 90)A
Ukuqhawuka kwamandla : 3KA
3, uMgangatho weMveliso:NFC 62412,IEC60947
4, Mounting Imeko
1) Ubushushu bomoya okwindawo yokuhlala
1) Ukuqwalasela ubushushu obugqithisileyo be-ambient ukukhawulezisa ukuguga kwamalungu eplastiki, umda ophezulu awukho ngaphezu kwe +40 ℃.
Ukuqwalasela ukuba iqondo lobushushu elisezantsi kakhulu ngokugqithisileyo
utshintsha ukulingana kwelungu lolwakhiwo, umda osezantsi awukho ngaphantsi kwe -5℃.
Ukuqwalasela ubomi benkonzo ye-breaker circuit, ixabiso eliqhelekileyo leeyure ze-24 alikho ngaphezu kwe-+35 ℃.

Phawula:

① Imeko yokusebenza yexabiso eliphantsi lomda ngu -10℃ okanye -25℃.Umsebenzisi kufuneka abhengeze kwinkampani xa eodola.
②Imeko yokusebenza yexabiso lomda ophezulu ogqithisa +40℃ okanye ixabiso elisezantsi lomda ongaphantsi kune -25℃, umsebenzisi kufuneka axoxisane nenkampani.
2)Indawo yokufakela
Ukuphakama akudluli kwi-2000m;
Iimfuno zesekethe yokhuseleko;
Indawo yokufaka ibala i-short circuit current current Ik ayikho ngaphezu kwe-3000A;
I-breaker circuit iya kufakwa ngokuhambelana neemfuno zokusetyenziswa kwencwadi, ukuthambekela okuthe nkqo kwe-circuit breaker akuyi kudlula i-5 °, Ukutshatyalaliswa kokusingqongileyo akukho ngaphezu kwe-5g.
3) Iimeko ze-Atmospheric
Ukufuma kwe-atmosphere akudluli kwi-50% kwiqondo lokushisa lomoya we-ambient +40 ° C.Umyinge wenyanga ubuninzi bokufuma obuphezulu benyanga emanzi kakhulu yi-90%, kunye neqondo lokushisa elisezantsi lenyanga yi +25 ° C kwaye uthathele ingqalelo ukuxinana kumphezulu wemveliso ngenxa yokutshintsha kobushushu.
4) Inqanaba longcoliseko
Inqanaba longcoliseko linqanaba lesi-3.
5) ICandelo loFakelo
Isiphaluka sokukhusela i-circuit breaker ifakwe kwicandelo III.
6)Icandelo lomnqamlezo wocingo liqulunqwe ngokuhambelana nobuninzi obuqhelekileyo bokufudumala okwangoku Ith ye-breaker circuit.
