Outdoor High-Voltage Intelligent Sectionalizing Vacuum Circuit Breaker ZW20-12F price_Manufacturer_How much

Overview:

The ZW20-12F outdoor high-voltage intelligent sectionalizing vacuum circuit breaker is designed for a rated voltage of 12kV and a three-phase AC system with a frequency of 50Hz. It is primarily used for breaking and closing load currents, overload currents, and short-circuit currents in power systems.

This circuit breaker is suitable for protection and control in substations, industrial and mining enterprises, as well as urban and rural distribution networks. It is especially well-suited for frequently operated environments and automated urban distribution networks. When paired with a controller, this product can meet the requirements of distribution automation systems and reliably and effectively perform the functions traditionally associated with reclosers.

Environmental Conditions:

Altitude not exceeding 3000 meters;
Ambient air temperature: -40°C to +40°C; daily temperature variation: 25°C;
Wind speed not exceeding 35 m/s;
Free from flammable, explosive hazards, strong chemical corrosive substances (such as various acids, alkalis, or dense smoke), and severe vibration environments.
