China MCB FTCQP 1 Pole 20A TPN MCB I 50Hz Electrical Miniature Circuit Breaker ifektri kunye nabavelisi

I-MCB FTCQP 1 I-Pole 20A TPN MCB I-50Hz yoMbane oMncinci weSaphuli seSekethe esibonakalayo

I-MCB FTCQP 1 Ipali 20A TPN MCB I-50Hz yoMbane oMncinci weSaphuli seSekethe

Inkcazelo emfutshane:

1. Isicelo: Ukukhusela iintambo kunye nezixhobo ngokuchasene nokugcwala kunye nesekethe emfutshane.

2. Imigaqo ngokubanzi yokukhetha i-MCB.

a. Idatha yobugcisa yothungelwano kwindawo eqwalaselwayo: Iinkqubo zomhlaba, i-short-circuit current kwindawo yofakelo lwe-breaker circuit, ekufuneka ihlale ingaphantsi komthamo wokuphulwa kwesi sixhobo, inethiwekhi yombane eqhelekileyo.

b. Kukho iimpawu ze-3 ze-curve yokusebenza kwamagnetic: i-B curve (3-5 In) ukukhusela kunye nokulawulwa kweesekethe malunga neentambo zobude kwiinkqubo ze-TN kunye ne-IT.

c. igophe (5-10 In) ukhuseleko kunye nolawulo lweesekethe ngokuchasene nomthwalo ogqithisiweyo kunye neesekethe ezimfutshane; ukukhuselwa kwemithwalo yokumelana kunye ne-inductive kunye ne-low inrush current.

I-Dcurve (10-20 In) ukukhuselwa kunye nokulawulwa kweesekethe ngokuchasene nokugqithisa kunye neesekethe ezimfutshane; ukukhuselwa kweesekethe ezibonelela ngemithwalo nge-inrush current ephezulu ekuvaleni kwesekethe (i-LV/LV transformers, izibane zokuqhawula).
