ZW7-40.5 Outdoor Vacuum Circuit Breaker
overview
ZW7-40.5 outdoor high-voltage vacuum circuit breaker is used in the three-phase power system with AC 50Hz and voltage 40.5, and is used for breaking and closing load current, overload current and short-circuit current.
The main function
Vacuum arc extinguishing is adopted, with strong breaking capacity, long electrical life and mechanical life of 10,000 times;
Simple structure, maintenance-free, no long maintenance period;
Good insulation performance, strong anti-pollution ability;
Equipped with spring or electromagnetic operating mechanism, the mechanical performance is reliable and can be operated frequently;
No fire and explosion hazards; built-in current transformer, the accuracy reaches 0.2 level, and can realize three-phase interactive protection;
The built-in condensation controller can keep the circuit breaker running reliably under certain temperature and humidity.
