ZN85 40.5kV Indoor Vacuum Circuit Breaker Modular Type

ZN85 40.5A Indoor Vacuum Circuit Breaker Modular Type


1. ZN85 40.5a indoor vacuum circuit breaker introduction


ZN85 40.5A Indoor Vacuum Circuit Breaker is suitable for three-phase AC 50Hz power systems, applicable to
industrial and mining enterprises, power plants and substations for breaking and closing load current, overload current and
short-circuit current. The composite insulation structure is adopted to meet the insulation requirements under normal operating
conditions, effectively reducing the volume of the circuit breaker


2. Environmental conditions:


1. Altitude: the altitude does not exceed 2000m;

2. Ambient temperature: no higher than +40℃, not lower than -25℃;

3. Relative humidity: the daily average does not exceed 95%, and the monthly average does not exceed 90%;

4. Earthquake intensity: no more than 8 degrees;


3. Structural features:


1. The ZN85 40.5A Indoor Vacuum Circuit Breaker adopts the arc extinguishing chamber on the upper part, and the structure of the whole structure under the mechanism is favorable for debugging;

2. It adopts composite insulation structure of air and organic materials, which is compact in design and light in weight;

3. It can be equipped with the vacuum interrupter of Cutler-Hammer Company of the United States and the domestic ZMD vacuum interrupter. The two arc extinguishing chambers adopt the longitudinal magnetic field arc extinguishing, low interception and good asymmetric breaking performance.
