Uhlobo Olusha lwe-CJRV-32X MPCB 25-32A Motor Protection Circuit Breaker

Incazelo emfushane:

I-CJRV series AC Motor protection circuit breaker ifanelekela amasekethe ane-AC voltage efika ku-690V kanye ne-current efika ku-80A. Isetshenziselwa ukulayisha ngokweqile, ukwehluleka kwesigaba, ukuvikelwa kwesifunda esifushane, kanye nokulawula kokuqala okungajwayelekile kwama-motor angenasilinganiselo ekheji le-squirrel anezigaba ezintathu. Ingasetshenziswa ekuvikeleni imigqa yokusabalalisa kanye nokushintsha umthwalo okungajwayelekile, futhi ingasetshenziswa njenge-isolator.

Izimo zokusebenza nokufakwa ezijwayelekile

Ukuphakama kwendawo yokufaka ngokuvamile akudluli ku-2000m;
Umkhawulo ophansi wokushisa komoya okuzungezile ngokuvamile awuphansi kune--5 ℃, umkhawulo ophezulu ngokuvamile awuphakeme kune-+40℃, futhi inani lawo elimaphakathi lingakapheli amahora angama-24 alidluli+35 ℃;
Umswakama womoya akufanele udlule u-90% (ku-+25 ℃ ± 5 ℃)
Izinga lokungcoliswa kwemvelo ezungezile liyizinga lesi-3 lokungcoliswa;
Isigaba sokufaka sesiqalisi yisigaba sokufaka lll;
Ukuthambekela phakathi kwesiqalisi kanye nobuso bokufaka obuqondile akumele kudlule ± 5 °;
Izinga lokukhubeka: CJRV-25 (X),CJRV-32 (X),CJRV-32H,CJRV-80:10A;
Amahora okusebenza alinganiselwe: amahora okusebenza angaphazanyiswa, amahora okusebenza angamahora ayisishiyagalombili.
