Whakaahuatanga Poto:

Whakaahuatanga Hua
He pai te taputapu tiaki ngaru raupapa CJ-T2-20 SPD mō te TN-S, TN-CS, TT, IT me ētahi atu, pūnaha tuku hiko AC 50/60Hz, ≤380V, kua tāutahia ki te hononga o LPZ1, LPZ2 rānei me LPZ3, kua hangaia kia rite ki te lEC61643-1, GB18802.1, e whakamahi ana i te rēri paerewa 35mm, he tukunga rahunga kei runga i te kōwae o te taputapu tiaki ngaru. Ina rahua te SPD i te pakaru nā te wera nui me te iahiko nui, ka āwhina te tukunga rahunga i te taputapu hiko kia wehe i te pūnaha hiko ka hoatu he tohu tohu, ko te tikanga o te kakariki he noa, ko te tikanga o te whero he rerekē, ka taea hoki te whakakapi mō te kōwae ina he ngaohiko whakahaere.
