Overview:

The ZW32-40.5F(M) outdoor high-voltage intelligent (permanent magnet) vacuum circuit breaker primarily consists of integrated solid-sealed poles, current transformers, an operating mechanism, and a steel enclosure. An isolation switch can be added if needed. This circuit breaker is designed with compactness in mind, using a high-quality steel box for its casing. The current transformer can be selected based on user requirements.

This device is mainly used in medium-voltage overhead line networks for breaking and closing load currents, overload currents, and short-circuit currents.

Operating Conditions:

• Ambient air temperature: -30°C to +60°C;
• Altitude: not exceeding 3000 meters;
• Wind speed: not exceeding 34 m/s;
• External vibrations or ground movements affecting the switchgear and control equipment are negligible;
• Pollution level: Grade IV;
• Storage temperature: -40°C to +85°C.
