Product Detail

Khoom cim npe

FN5-12 hom sab hauv tsev AC high voltage load brek hloov (Ntawm no hu ua load so switch) txiv apples rau AC 50Hz 12kV network, rau kev tawg tam sim no thiab kaw luv luv tam sim no. Load break hloov nrog fuse tuaj yeem txiav tawm luv luv tam sim no rau kev tiv thaiv kev hloov.

Lub load so hloov siv tau nrog CS6-1 hom phau ntawv kev khiav hauj lwm mechanism, thiab cov khoom no tshwj xeeb siv CS phau ntawv khiav hauj lwm mechanism.

Daim ntawv thov

FN5-12 hom sab hauv tsev AC high voltage load break switch (Ntawm no hu ua load break switch) siv rau AC 50Hz 12kV network, rau kev tawg tam sim no thiab kaw luv luv tam sim no. Load break hloov nrog fuse tuaj yeem txiav tawm luv luv tam sim no rau kev tiv thaiv kev hloov.

Kev hloov pauv hloov pauv tuaj yeem siv nrog CS6-1 hom kev tuav tswj kev ua haujlwm, thiab cov khoom siv tshwj xeeb no siv CSqhov ncaujphau ntawv ua haujlwm mechanism.
