Overview:

The ZW20-12F(M) outdoor high-voltage intelligent (permanent magnet) vacuum circuit breaker is designed for a rated voltage of 12kV and operates in three-phase AC systems with a frequency of 50/60Hz. 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 environments with frequent operations 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.

Operating Conditions:

• Ambient temperature: not exceeding 40°C; daily average temperature not exceeding 35°C; minimum surrounding air temperature of -25°C;
• Relative humidity: daily average not exceeding 95%, monthly average not exceeding 90%; daily average vapor pressure not exceeding 2.2 kPa, monthly average not exceeding 1.8 kPa;
• Altitude: not exceeding 2000 meters;
• The surrounding environment is free from significant pollution by dust, smoke, corrosive and/or flammable gases, vapors, or salt spray;
• External vibrations or ground movements affecting the switchgear and control equipment are negligible;
• Induced electromagnetic interference in the secondary system does not exceed 1.6kV.
