ZN63-24 Indoor High-voltage Vacuum Circuit Breaker

Indoor switching equipment for three-phase AC 50 Hz, 24 kV systems, protecting and controlling network and industrial equipment. Suitable for frequent operation at rated current or repeated short-circuit interruption. The operating mechanism and breaker body are integrated; available as a fixed unit or with a dedicated insertion mechanism for a withdrawable truck. Conditions: −15 to +40°C, altitude ≤1000 m; higher altitudes require increased insulation levels. Daily/monthly relative humidity ≤95%/90%, earthquake intensity ≤8; no fire/explosion hazards, severe pollution, corrosion or vibration.
