ZW32-24 Outdoor Vacuum Circuit Breaker

The ZW32-24 is an outdoor vacuum circuit breaker rated for 24 kV, three-phase AC 50 Hz distribution systems. It handles breaking and closing of load current, overload current, and short-circuit current, and is applied at substations and industrial and mining enterprise power systems for protection and control — particularly suited to rural power grids and applications requiring frequent operation.

Available in 16 / 20 / 25 kA breaking current tiers with 630 A / 1250 A current ratings, the ZW32-24 steps up from the 12 kV ZW32 series to serve higher-voltage outdoor feeder and substation applications, with IV-class pollution rating for harsher outdoor environments.
