ʻO ka VYC Type Center-mounted Vacuum Contactor-Fuse Combination Electrical Appliance he kūpono ia no nā lako hoʻololi o loko me ka volta helu o 3.6-12 kV a me kahi alapine AC ʻekolu o 50 Hz.
Hoʻolālā ʻia kēia huahana no nā wahi e koi ana i ka haki kaapuni pinepine a me nā hana pani.
Hiki iā ia ke hoʻokō i nā koi o ka mea hoʻohana no nā hana maʻamau a loaʻa iā ia nā pōmaikaʻi e like me ke ola lōʻihi, ka hana paʻa, a me ka hana kūpono.
He kūpono ia no nā keʻena switchgear i kau ʻia ma waena me 650mm a me 800mm ākea.
Hoʻohana ʻia ia i nā ʻoihana ʻenehana a me nā ʻoihana mining e like me ka metallurgy, petrochemical, a me ka mining.
Hoʻohana ʻia ia e hoʻomalu a pale aku i nā motika kiʻekiʻe-voltage, nā hoʻololi pinepine ʻana, nā umu induction, a me nā mea hoʻololi ukana ʻē aʻe.
Kūlana: IEC60470:1999.
