I-YUANKY MCB 1-63A 240/415V AC 1p 2p 3p 4P iec60898 i-BCD curve mini air circuit breaker

Inkcazo emfutshane:

Jikelele

S7 inomda ophezulu wamandla ombane ukunciphisa amandla okutshatyalaliswa ngenxa ye-short circuit eya kwi- ubukhulu becala. Isicelo: Ukukhusela iintambo kunye nezixhobots ngokuchasene nokugqithisa kakhulu kunye nokujikeleza okufutshane.

Imithetho ngokubanzi yokukhetha i-MCB.

Idatha yobugcisa yenethiwekhi kwindawo eqwalaselweyo:

Iinkqubo zokumba umhlaba, umsinga we-short-circuit kwindawo yokufakela i-circuit breaker. soloko unjalo ngaphantsi komthamo wokuqhekeka kwesi sixhobo, i-network voltage eqhelekileyo.

Kukho iimpawu ezi-3 zegophe lokusebenza kwemagnethi:

Ukhuselo kunye nolawulo lwe-B curve (3-5In) yeesekethe ngokuchasene neentambo zobude kwi-TN kunye ne-IT SYSTEMS.

Ukhuselo kunye nolawulo lwe-C curve (5-10In) yeesekethe ngokuchasene nokugqithisa kunye neesekethe ezimfutshane; ukhuseleko kwimithwalo ekhuselayo nebangela ukungasebenzi kakuhle ene-inrush current ephantsi.

Ukhuselo kunye nolawulo lwe-D curve (10-20In) yeesekethe ngokuchasene ne-overloads short-circuits; ukhuseleko kwiisekethe ezibonelela ngemithwalo ene-inrush current ephezulu kwi the ukuvalwa kwesekethe (LV/LV iitransformer, izibane zokuqhekeka).
