Indoor high voltage vacuum circuit breaker
Description:
*ZN85-40.5/T2000-31.5 Indoor High Voltage Vacuum Circuit Breaker, suitable for three-phase AC 50Hz, rated voltage 40.5KV power system.
*It can be used for separating and combining load current, overload current and fault current in industrial and mining enterprises, power plants and substations.
*The circuit breaker is connected with the operating mechanism by the upper and lower arrangement structure, which effectively reduces the depth of the circuit breaker.
*A spring operation mechanism specially designed for this new type of circuit breaker is installed in the frame of the circuit breaker.
*Its structural characteristics are more suitable for the upper and lower layout of the circuit breaker, and become an integral part of the overall structure of the circuit breaker.
*The design is simple, the output curve and its performance are more suitable for the characteristics and requirements of 40.5kV vacuum circuit breaker.
*The circuit breaker is suitable for frequency operation and a variety of occasions and operating conditions are more stringent places.
