O le ZN23-40.5 o loʻo i totonu o le fale eletise maualuga volitiga motusia o le autu switchgear o 40.5KV tolu vaega AC 50Hz e talafeagai mo le puleaina ma le puipuia o le tufatufaina o faiga o pisinisi alamanuia, substationm faʻapitoa mo metallurgy pisinisi lea e manaʻomia tele faʻagaioia eletise ogaumu uila.
O lenei breaker usitaʻia le manaʻoga o le GB1984-89 "AC Ese voltage voltage soli" breaker aveina mafai ona tuleia i totonu GBC-35, JYN1-35 maualuga voltage switchboard, pe a fai o le plug o breaker e aveʻesea, e mafai ona faʻagaeʻetia tutoʻatasi.
