Ikhabhinethi yenethiwekhi yendandatho ihlanganiswe ngephrofayili engu-8MF, kanti imbobo yemodulus E = 20mm ifakiwe kuhlaka lonke. Iswishi yomthwalo wohlobo lwe-FZN21-12D noma inhlanganisela yefuse yohlobo lwe-FZRN21-12D ifakwe kukhabhinethi yenethiwekhi yendandatho. Lolu hlobo lwedivayisi kagesi luneswishi yomthwalo we-vacuum yokuxhuma i-disconnecting switch, i-grounding half-opening, kanye neswishi yokuxhuma i-disconnecting kanye neswishi yokuxhuma i-grounding inezimfa ezisobala.
Iswishi yokuzihlukanisa, iswishi yomthwalo we-vacuum, iswishi yokumisa kanye nomnyango wekhabhinethi inezixhumanisi eziphelele zemishini kanye namadivayisi axhumene, angavimbela ngempumelelo ukusebenza kabi futhi aqinisekise ukulungiswa okuphephile.
Ingasetshenziswa ngesandla nangogesi. Umnyango wekhabhinethi yokulinganisa kanye nomnyango wezinsimbi unikezwa izikhonkwane zokuvala i-lead.
