The ZW62-12 integrated primary-secondary pole-mounted circuit breaker is a 12kV-rated, three-phase, 50Hz outdoor power distribution equipment. This switch adopts vacuum arc extinguishing technology as its interrupting medium. It is primarily used for making and breaking load current, overload current, and short-circuit current in power systems. Suitable for protection and control applications in substations and industrial power distribution systems, it is particularly well-adapted for rural power grids and sites requiring frequent operations. The matching intelligent controller integrates protection, monitoring, and control functions into a single unit, fully meeting the requirements of distribution automation systems while reliably and effectively performing traditional recloser functions.
