FN5-12 mhando yemukati AC yakakwira voltage load brek switch (Pano yakazonzi load break switch) maapuro kuAC 50Hz 12kV network, yekupwanya mitoro iripo uye kuvhara mapfupi redunhu ikozvino. Load break switch ine fuse inogona kucheka ipfupi redunhu ikozvino yekudzivirira switch.

Iyo yekuremerwa break switch inogona kushandiswa neCS6-1 mhando yemanyorero ekushandisa, uye ichi chigadzirwa chakakosha chinoshandisa CS bhuku rekushandisa.

Application

FN5-12 mhando yemukati AC yakakwira voltage load break switch (Pano inonzi load break switch) inoshanda kune AC 50Hz 12kV network, yekupwanya mitoro iripo uye kuvhara pfupi redunhu ikozvino. Load break switch ine fuse inogona kucheka ipfupi redunhu ikozvino yekudzivirira switch.

Iyo yekuremerwa break switch inogona kushandiswa neCS6-1 mhando yemanyorero ekushandisa, uye ichi chigadzirwa chakakosha chinoshandisa CSmuromomanual operating mechanism.
