ZW32-40.5 Outdoor Pole Mounted Vacuum Circuit Breaker | 35kV High Voltage Auto Recloser
The ZW32-40.5 Series Outdoor Vacuum Circuit Breaker is designed for three-phase power systems with a rated voltage of 35kV and AC 50Hz. It serves as an essential protective component for separating and combining load currents, overload currents, and short-circuit currents. This pole-mounted breaker can be integrated with a reclosing controller to function as an intelligent auto-recloser, capable of identifying current characteristics and performing multiple automatic reclosing sequences. Equipped with an electronic PT for power supply and signal output, it provides advanced three-stage composite protection, including overcurrent, inrush current, and short-circuit quick-break delays.
