I-MCB FTCQP 1 Pole 20A TPN MCB I-50Hz Electrical Miniature Circuit Breaker

Inkcazo emfutshane:

1. Ukusetyenziswa: Ukukhusela iintambo kunye nezixhobo kwi-overload kunye ne-short circuit.

2. Imithetho ngokubanzi yokukhetha i-MCB.

a. Idatha yobuchwephesha yenethiwekhi kwindawo eqwalaselwayo: Iinkqubo zokumba umhlaba, umsinga wesekethe emfutshane kwindawo yokufakela i-circuit breaker, ekufuneka ihlale ingaphantsi komthamo wokuphuka kwesi sixhobo, i-network normal voltage.

b. Kukho iimpawu zegophe ezintathu zokusebenza kwemagnethi: Ukhuselo lwegophe le-B (3-5 In) kunye nolawulo lweesekethe ngokuchasene neentambo zobude kwiinkqubo ze-TN kunye ne-IT.

c. ukhuselo kunye nolawulo lwe-curve (5-10 In) yeesekethe ngokuchasene nokugqithisa kunye nee-short-circuits; ukhuseleko kwimithwalo ekhuselayo kunye neyokungenisa ene-inrush ephantsi.

Ukhuseleko kunye nolawulo lweesekethe ze-Dcurve (10-20 In) ngokuchasene nokugqithisa kunye neesekethe ezimfutshane; ukhuseleko lweesekethe ezibonelela ngemithwalo ene-inrush current ephezulu xa kuvalwa isekethe (ii-transformers ze-LV/LV, izibane ze-breakdown).
