Uhlobo olutsha lweCJRV-32X MPCB 25-32A Motor Protection Circuit Breaker

Inkcazo emfutshane:

I-CJRV series AC Motor protection circuit breaker ifanelekile kwiisekethe ezine-AC voltage ukuya kuthi ga kwi-690V kunye ne-current ukuya kuthi ga kwi-80A. Isetyenziselwa ukugqithisa kakhulu, ukungaphumeleli kwesigaba, ukhuseleko lwesekethe emfutshane, kunye nolawulo olungaqhelekanga lokuqalisa lwee-motor ze-squirrel cage zesigaba sesithathu. Ingasetyenziselwa ukukhusela umgca wokusasazwa kunye nokutshintsha umthwalo rhoqo, kwaye ingasetyenziswa njenge-isolator.
