ZW32-24 Outdoor High-Voltage Vacuum Circuit Breaker

Overview:

The ZW32-24 Outdoor Vacuum Circuit Breaker is a reliable power distribution device designed for a rated voltage of 24kV and a three-phase AC 50Hz power system. It is primarily used for making and breaking load currents, overload currents, and short-circuit currents within power systems. This breaker is ideal for protection and control in substations, as well as in the power distribution systems of industrial and mining enterprises, particularly in rural areas with frequent grid operations.

The circuit breaker is characterized by its compact size, lightweight design, anti-condensation features, and maintenance-free operation. It is engineered to withstand harsh climatic conditions and dirty environments, ensuring reliable performance in demanding settings.
