Overview
The ZN85-40.5 handcart type vacuum circuit breaker stands as a pinnacle of indoor high-voltage switchgear technology, tailored for three-phase AC systems operating at 50Hz and rated at 40.5kV. This pivotal device serves industrial and mining enterprises, power generation facilities, and electrical substations, adeptly managing load currents, overload currents, and fault currents, especially in scenarios demanding frequent operation. Its design, manufacturing, and testing processes adhere strictly to the GB/T 11022-1999 standards and other relevant criteria, ensuring unparalleled performance and safety..
Environmental Conditions
The upper limit of ambient temperature is +40C, and the average value measured within 24 hours does not exceed 35C; Lower limit -15℃.
The altitude does not exceed 1000m.
Relative humidity: the daily average does not exceed 95% The monthly average value does not exceed 90%.
Water vapor pressure: daily average does not exceed 2.2kPa, monthly average does not exceed 1.8kPa.
The surrounding air is not significantly contaminated by dust, smoke, corrosive or combustible gases, vapors and salt spray.
When used under the above normal environment and other conditions specified in GB/T11022-1999, the user can negotiate with the manufacturer to solve the problem.
Product Features
Advanced Arc Extinguishing and Power Interruption: Leveraging cutting-edge vacuum arc extinguishing technology, this circuit breaker minimizes arc duration and enhances power interruption capabilities, facilitating stable system operations.
Robust Handcart Structure for Enhanced Safety: Its handcart design simplifies installation and maintenance processes, incorporating "five-prevention" safety features to safeguard operators.
