| Serye | DNH8(HGL) |
Ang serye ng Pole Isolator Switches DNH8(HGL) ay disenyo para sa iba't ibang aplikasyon kung saan kinakailangan ang pagbukas at pagsara ng circuit o elektrikal na paghihiwalay. Ang mga ito ay magagamit sa pitong iba't ibang modelo, mula 63A hanggang 3150A, at mayroong modular na disenyo na may tatlong at apat na antas (tatlong antas + neutral na antas para sa pagbukas at pagsara).
Ang switch na ito para sa elektrikal na paghihiwalay ay may front-side window na nagpapakita ng estado ng contact na on/off, at isang rear observation window na nagbibigay-daan sa direkta na obserbasyon ng estado ng contact na on-off.
Range ng Temperatura: Ang temperatura ng hangin sa paligid ay dapat manatili sa pagitan ng -5 °C at +40 °C, na ang relasyon ng humidity ay hindi lumalampas sa 95%.
Altitude: Ang altitude ng instalasyon ay hindi dapat lumampas sa 2000 metro.
Kalikasan ng Kapaligiran: Ang switch ay dapat gamitin sa mga lugar na walang panganib ng pagsabog at kung saan ang ulan o niye ay hindi makakapasok.

Ang serye DNH8(HGL) na may tatlong phase isolator switch ay nagbibigay ng mahalagang pagganap para sa electrical isolation at circuit control sa iba't ibang aplikasyon. Magkakaroon ito ng mga modelo mula 63A hanggang 3150A, ang disenyo na ito ay modular na may tatlo at apat na lebel (kasama ang neutral level para sa operasyon ng circuit). Bukod dito, mayroon itong front-side window para ipakita ang estado ng contact at isang rear observation window para sa madaling monitoring.
