Latin Edition ZW8-12 velit altum voltage vacuum ruptor est principalis switch apparatu in circuitu rated 12KV voltage, Adscriptio tres gradus comprehendit AC50Hz ratio ut switch super / off loading current, super-current et in brevi circuitu rustica vel urbana network potestate. In structuram et convenerunt ruptor est three-tempus in piscinam, three-tempus in vacuo metallum arcus conclusus, tristique sit exstinguere aethereum thalamum, Nulla materia ad tempus, et tempora inter se e SMC, reliable ex personatis; et magno robore insulating.

ZW8-12G ruptor consistit ex ZW8-12 et isolator, nomine ruptor nigredine mixta, potest esse quod sectionalizer.

Ruptor seriem operating A mechanism hoc est vere stultum quid contra CT23 mechanism, motricium seu manum operating genus.
