YUANKY MCB 1-63A 240/415V AC 1p 2p 3p 4P iec60898 BCD ijiko elincinci lomoya wesaphuli sesekethe

Inkcazelo emfutshane:

Ngokubanzi

S7 yeyomsebenzi ophezulu wokunciphisa wangoku ukunciphisa amandla okutshatyalaliswa ngenxa yesiphaluka esifutshane ukuya ubukhulu obukhulu. Isicelo:Ukukhusela iintambo kunye nezixhobots ngokuchasene nokugcwala kunye nesekethe emfutshane.

Imigaqo ngokubanzi yokukhetha i-MCB.

Idatha yobuchwephesha bothungelwano kwindawo eqwalaselweyo:

Iinkqubo zomhlaba, i-short-circuit current kwindawo yokufakela i-circuit breaker. ekufuneka njalo ngaphantsi komthamo wokuqhawuka kwesi sixhobo, inethiwekhi yombane eqhelekileyo.

Kukho iimpawu ezi-3 zegophe yokusebenza kwemagnethi:

I-B curve (3-5In) ukukhusela kunye nokulawulwa kweesekethe malunga neentambo zobude kwi-TN kunye ne-IT SYSTEMS.

I-C curve (5-10In) ukukhuselwa kunye nokulawulwa kweesekethe ngokuchasene nokugqithisa kunye neesekethe ezimfutshane; ukukhuselwa kwemithwalo yokumelana kunye ne-inductive kunye ne-low inrush current.

I-D curve (10-20In) ukhuseleko kunye nolawulo lweesekethe ngokuchasene nokugqithiswa kweesekethe ezimfutshane; ukhuseleko kwiisekethe ezinikezela ngemithwalo nge-inrush yangoku ephezulu the ukuvalwa kwesekethe (LV/LV iziguquli, izibane eziqhekezayo).
